Use Flagdata In Dynamic Role

Is it possible to use flag data in a dynamic role's formula?

In v7.6 it was possible to set a variable equal to a flag paramater data and then define the dynamic role as the variable, but in v9 we only have access to the ProcessContext, thus cannot use a variable.

Is there another way, other than writing the data to a DB field, to use data from a flag (or variable) in a dynamic role formula?
