hold
#35757 does the same work

[cmsbuild]

Pull request has been put on hold by @Dr15Jones
They need to issue an unhold command to remove the hold state or L1 can unhold it for all

[perrotta]

@Dr15Jones now that #35757 is merged in 12_0, can we close this (to clean up the queue)?

[Dr15Jones]

superseded by #35757
