Setting a player to FA using Import Player method

Is it possible to change a player that is on a team to become a fa using the player import?
Example - Team for this player is set to two -> changing this to "0" ignores moving them to FA, where changing it to "3" moves the player to the new team.
{"Players":[{"Id":2429,"Sea":2003,"Rook":2001,"First":"Jeff","Last":"Harbin","Team":"2","DRnd":
My assumption is (1) this is not supported to move off a team or (2) I would need to set to some other string to indicate a FA status.
Can this be done, and if so how?
Cheers!
