As far as I'm aware, no - and its probably not that simple to manually
either (not and retain the nice clean 1 sub-sheet for all modules).

For this sort of situation, I've tended to use that very raw,
"copy-paste the circuit" approach and explicitly set the slot number.

Certainly your requirement is one which has been considered for future
improvement, but unfortunately it requires a reasonable amount of
changes to implement. Once it is possible to override arbitrary
attributes nested within a sub-circuit, it will be as simple as
resetting the slot=xxx attribute down inside the sub-circuit for each
instance you have.
