Getting the number of possible outputs from a decision table

Is it possible to automatically retrieve/let DMN calculate the total number of possible outputs from a decision table in FEEL notation?
I have a definition with a collect rule in a 7x8 (column x row) decision table and want to quickly gather a complexity estimation from that definition.
Simply counting rules won’t work, as I need to take into account the logic defined in those rules.
Does the API provide any such functionality here?
