I agree - this is a right pain.
This is an area in Planet Coaster I don't get, why things don't adhere to a standard. As an ex-programmer myself, we would use "common code" to (in this case), display a list of items. You would use the same code and pass it a different list whenever you want to do this but this doesn't happen in Planet Coaster.
There are other anomalies like this too which I am sure we have all come across (ride signs for some rides but not all, in consistent colouring of items etc etc.
Doesn't make sense to me. Gives the program a "half finished" feel if you ask me which is a shame as love Planet Coaster!
