Google Apps 脚本：通过从 Google 表格中的数据搜索文件夹名称来将文档创建到特定文件夹中？

The Situation: I have data on a Google Sheet. I am using that data to fill in a template Google Doc, and the newly-created Doc needs to be saved into a specific Google Drive folder based on two criteria. The criteria are a Name and a Month, both of which are variables on the Sheet.

The Problem: I can\'t figure out how to save the doc in the right place, or if it\'s even possible with Google Apps Script / Google Drive. Two of the columns in my Sheet have data with a person\'s Name and Month. I want to search first for a folder by Name, and then within that folder, I want to search by Month using the row data from the Sheet. The doc would be saved into this Month subfolder within the Name folder.

Current State: My code pulls data from the Sheet, inserts it into the template, and names the new doc what I tell it to. I was able to tell it where to save this new doc using

const destinationFolder = DriveApp.getFolderById(\'ID_GOES_HERE\');

but there are multiple Names and multiple Months, so I can\'t use IDs for all of them. I want the code to dynamically find the correct subfolder based on Name and Month variable in the Sheet.

Is this even possible?

Here\'s a snip of my current code, I removed IDs and such for anonymity:

/* Creates a menu item in the Spreadsheet that triggers population of the coaching package documents. */
function onOpen() {
  const ui = SpreadsheetApp.getUi();
  const menu = ui.createMenu(\'AutoFill Template\');
  menu.addItem(\'Create New Document\', \'createNewGoogleDocs\');
  menu.addToUi();
}

/* Loops through spreadsheet rows. If there is no Document Link, a new document will be generated. */
function createNewGoogleDocs() {

  const googleDocTemplate = DriveApp.getFileById(\'ID_GOES_HERE\');
  const destinationFolder = DriveApp.getFolderById(\'ID_GOES_HERE\');
  const sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(\'Responses\');
  const rows = sheet.getDataRange().getValues();
  
  rows.forEach(function(row, index) {
    if (index === 0) return;
    if (row[13]) return;

    const copy = googleDocTemplate.makeCopy(`QCP - ${row[4]} - ${row[2]}`, destinationFolder);
    const doc = DocumentApp.openById(copy.getId());
    const body = doc.getBody();

    body.replaceText(\'{{Title Name}}\', row[4]);
    body.replaceText(\'{{Month}}\', row[2]);
    body.replaceText(\'{{Name}}\', row[3]);
    body.replaceText(\'{{Desired 1}}\', row[5]);
    body.replaceText(\'{{Desired 2}}\', row[6]);

    doc.saveAndClose();
    const url = doc.getUrl();
    sheet.getRange(index + 1, 14).setValue(url);
  });
}

EDIT for anyone who has a similar problem in the future, this was my result! Thank you to both Mike and Yuri.

    const parent_folder = DriveApp.getFoldersByName(row[3]).next();
    const subfolder = parent_folder.getFoldersByName(row[2]).next();
    const destinationFolder = DriveApp.getFoldersByName(subfolder).next();
