Request: Rename Option in Export Settings

[pefunk]

I would like to have the ability to re-name files on export, other than to type in a new filename with every single pic. Other software (On1, ACDSee, Lightroom, DxO) let you use a template to rename files and store that template as a preset in the export settings. E.g. attaach a date to the filename, or - in my case - just attacj _Aff to document what programme was used ( I use several). To type in that attachment during save with each and every file can become tedious.
