Is purchasing setups allowed in doomsday speedruns? I know preps are, but i dunno if setups would be, and I'm not seeing anyone just buying them to skip.

The Cayo Perico Co-op WR has been pushed down to 19 mins by pre-stealing preps with other CEOs, then stealing them off of them.

Should this be allowed, if yes, could this be used for solo if we don't invite "helpers" into main heist?
