Yes, I think this is the sole raison d'etre for the SVC button!
In fact, depending on the outcome of this thread:

Might be unnecessarily cautious (i.e. the first whole-brain threshold
might be able to be 1 or near to it), or it might not... (though my
money is on the first threshold being unnecessary if you have an a
