Choosing Team builder roster, should send nfl players to Free Agency

I would greatly appreciate an option of sending the active NFL players I replace with the team builder team in franchise mode to free agency than have them disappear completely. Though i know not everyone would prefer that for a fully custom league.

Currently,  if you replace for example New York Giants with a team builder team, and select use team builder roster, all of the NFL players disappear. I would like the option to send the Former New York Giants to Free Agency.
