Removing default selected format

Hi all,

When I run the report FBL1N, and click on List - Export - Spreadsheet, I get a selection box to choose the format. When I choose a particular format and check the box "Always use selected format", the system always uses the same format to save the exported file.

Now the question is: I want the selection box to choose the format back.

If we go to table "SALV_BS_ADMIN" and delete the entry we can get back the selection box back, but I came to know that there is a programme for the same. Can any body help me with the programme.

Hope I made myself clear with what I am after.

Kevin.
