In the war room you can filter out kickers to remove the plethora of P and K; edit filter, "all except kicker".

Can this also be added to the Draft Class and Free Agent filter set?

It already is.

If you choose Player search, Position - all except kickers, then the team of Free Agents or Draft Class.

Agreed, but that's a roundabout way of doing it surely?

All the various methods of getting a list of players - draft, playersearch, free agents etc should surely all have consistent filters?
