I don't quite understand what you are asking here. Somewhere in your 
code you run the actual save panel, with what ever extensions you need. 
When this code returns you ask the save panel for the selected filename 
and file type. This surely isn't the problem.
Do you want to change the filename that is displayed in the save panel 
itself? This should be automatically adjusted when ever you select a 
different file type. I just tested with Ink and there this mechanism 
seems to work.
Most likely you are talking about a different problem that I fail to see.
