I'd like to configure my platform to request
from Gleba and request 


from Nauvis.
I'm not sure how to do this in the interface. There seems to be a way to configure separate tiers of requests but I don't know how to associate a request tier with a planet.
It sort-of works to leave it as-is, except I noticed it was trying to put iron plates on the Gleba rocket which seems counterproductive. I can stop that specific misbehavior but I'm wondering if there's a more general solution.
