How to rename the file while using the safelink

Hi All,

I have a file uploaded to sharepoint with encrypted file name ex: 1234.pdf .

I have the original name of the file stored in table and while providing a safelink for download , I need to replace 1234.pdf with original name from table. 

Currently safelink downloads the file with default/encrypted name of 1234.pdf .

What approach can be taken to have the file downloaded in original name. Please suggest.

Appreciate the help .

Note: if we download to Appian KC temporary and then rename the file, it will become a 2 step process. I would like to avoid that.

Thanks

Raj
