shapes-ISSUE-134 (knowing inverse): does SHACL syntax distinguish inverse property constraints [SHACL Spec]

Some constraint types require different SPARQL queries (or JavaScript or whatever) depending on the direction of a property (or even worse, for an arbitrary path). For example sh:minCount needs to count subjects versus objects.
Is it possible to determine whether a sh:minCount constraint is an inverse or not? Consider
ex:s a sh:Shape ;
sh:property _:c ;
sh:inverseProperty _:c .
_:c [ sh:predicate ex:p ;
sh:minCount 5 ] .
