Does RxNorm have "may treat" edges between drugs and indications?

Jennifer Hadlock mentioned this at the relay. Need to look into it. I don't see that we are catching this type of predicate, in predicate-remap.yaml. But maybe this information is, in fact, somewhere in umls-rxnorm.ttl or whatever.

Where were these seen outside of KG2? I am not seeing a "may treat" relation type on the RxNorm list of relationships here (or even a "treat" relation type for that matter).
