Deleting U23 squad from a team?

I'm using the level 23 English Pyramid database and starting a career with Tiverton Town in the Southern League Division One South/West, their reserve team plays in the Western League.

Is there any way to delete a team's U23 squad as currently Tiverton has 4 squads; First Team, Reserves, U23, and U18. The U23 squad is not there in real life so is it possible to remove it via the editor?
