Onslaught Tag Patch Coding?

[Kingxroyo]

If possible, is there a way to make a tag codes with Onslaught? I want to see if anyone knew a way or how. Im going to use Add004 for starters then Uno Tag Patcher. He will have his partner (Prime Sentinel or Sentinel) Fight first.

In one of his supers, he summons Sentinel to fight. I want to use the animation in that super and use it for his tag. He can spectate during the match

Please Help, its for an Upcoming Project.
