Send in Bulk: Do the PDF files of signed agreements have to be same name?

Hello experts,

I am wondering in Send in Bulk, when we were recieveing multiple signed PDF files from different signers, is it possible that we can have the returned Signed PDF's file named differently?  for example: [agreement's name]+[signer's name].pdf ?

Facing this problem is because it is very not a pleasant to find one specific signed PDF from bunch of PDF shared simular name.  (in the case of using external achieve, you can imagine... )

Looking forward to hear back.

Thanks!
