Am I missing something here, or is my maths all wrong.
If you want your tool to advance by 0.0002 (I assume this is the tooth dimension) on a two flute cutter, then at 6000 rpm the feed should be 2.4 units per minute - whether inches or mm does not matter - or am I way out.
In answer to the post, yes, it is possible to change the feed from units per min to units per rev, but this will involve you changing the GCode.
This might not be as difficult as it sounds, with the search and replace facility, but depending on who wrote the wizards, whether he (or she) would be willing to sit down and add it in would be up to them.
I think, however, if you work out accurately what movement you need, if you are fairly accurate with your spindle speed, and it does not vary overmuch (as in Constant Surface Speed work), then using this as a units per minute feed should not make any difference.
