Currently you can't launch a PSE simulation if you choose a parameter with GUID as a range param. You will get an error which says UUID objects are immutable.
This is because when you work with GID's as ranges, you don't have in interval on which you need to configure the simulation, but you run PSE over a list of objects. As an example for Connectivity we would need to obtain a list of GID's of all the connectivities that we want PSE to run on. First we should just let it run on all connectivities, and later we could add a filter to let us choose which connectivities do we want to include.
