@cartag thanks for responding! I'm dealing with the Horus Heresy catalogues, so my example is from there. A Rite of War requires EITHER a Veteran Tactical squad OR a Terminator squad when selected. So far, my only answer has been to give them both a shared entry link (Legion Veterans for instance) and make that shared entry required. However, another Rite of War also requires Veteran Tactical squads but not Terminator squads, so I'd have to give the Vets another separate shared entry to handle that. It gets ugly rather quickly, so I'm wondering if there's a smarter way to handle it.
