I would like to know if there's an option to allow optional input for the ProM plugin. Lets say I have a plugin that requires 4 inputs (A,B,C, and D), I wanted to make the first two mandatory, whereas the last two optional. I'd like to be able to choose to input either AB, ABC, ABD, or ABCD.
I wonder if ProM has any option to do so? Or do I need to create 4 plugins to cater for all the possibilities?
