Force trade option

Hi. I was wondering if there was a way to force trades or FA signings. One way I like to play is to replace an existing NFL team with an "expansion team" where I move the bench players of other teams and some FAs to the new team. I'd like to just trade the replaced teams players for the other players I want. Having that option will easily allow that and to keep up with the real world transactions like AB to the Patriots. Is there a way to do it or do I have to export to a CSV, make changes, and then re-import?
