I have no clue if this is a possibility in your system, but the commercial controls I used to work on had a simple drop-down that let you select if it was reverse acting or not. You could set the dampers to open or close based on energization(?) and select of they failed open or closed.
I have a feeling residential systems may be more limited. I have a zoned system at my house that works "meh" at best but I haven't had time to install a new system yet. Cobblers kids have no shoes kind of thing.😒
