File Data Set - Need to prevent Unique ID getting appended to File name

As we know files produced by File Data set are of below format

FileName-EnvNameUnique ID.Extension

CustomerDataExtract-Dev1232323232.CSV

I want to prevent these additional stuff from getting appended to Filename, I just want it as CustomerDataFileExtract.CSV, how to do achieve it.

anyone knows the name of the rule which forms the filename ?

@DilipanV105 In Pega, a File Data Set always adds the system name (your environment name) and a unique ID to the output file name to keep every run unique and avoid overwriting files.
That behavior is built into the File Data Set runtime, so there is no rule you can edit to stop or remove the suffix.
So you cannot produce a fixed name like CustomerDataFileExtract.csv directly from a File Data Set output.

@Sairohith They should make it optional, not mandatory.

Since there is no way to avoid the unique ID getting appended to FileName, I renamed the file after it got generated in the postActivity of the data flow using combination of D_pxListFiles, D_pxGetFile, D_pxNewFile, D_pxDeleteFile D Pages(API)
