Sync - S3 Destination - specifying subfolders and file naming options

We’re currently testing the S3 destination for various sources using CSV file format and would like to be able to do 2 things:

• Specify a subfolder per job or task
• Append the table name to the destination file

for example, if the S3 Connection is setup to a folder cdata/ i would like to be able to output the following structure

• cdata/
  • salesforce/
    • account/
      • account_20260722113426039_1.csv
      • account_20260722113426039_2.csv
    • contact/
      • contact_20260722113426039_1.csv
  • servicenow/
    • task/
      • task_20260722113426039_1.csv

..etc

The closest I’ve been able to get is appending something to the table/folder name, and I can’t find any usable option to control the file name format. I’ve tried changing the batch naming convention in the connection settings but it had no affect.

• cdata
  • salesforce_account
    • 20260722113426039_1.csv
    • 20260722113426039_2.csv

..etc

Additionally - Ther’es no documentation on the “Advanced” features of the S3 destination other than “you probably won’t need it” -- not a good look.
