A single data set might contain distinct process executions based on a certain attribute (Document type, Product Group , Workflow etc)
In these cases a single reference model to run the conformance on is not sufficient
Ideally we would be able to load multiple reference model to a data set and connect these to the data based on a given attribute (e.g Standard Order, Rush order, Intercompany Order, etc)
Just an idea but maybe the possibility to link a reference process to a given (set of) variant(s) would be helpful too. Of course this requires an enhancement in variant management(feature requests already existing).
