Pro3.1 - Force it to key number label everything

[KeithAddison1]

Is there a way to force Pro to use key numbering for all labels?  I crank the weight up to the max and turn off all other conflict resolution methods but it still refuse to key label everything.  It even leaves some labels unplaced instead of putting them into the key numbering scheme.

That's a setting in the key numbering window, rather than the individual label class.
