Can you import premiums?

Hello! 

Does anyone use premiums to track physical benefits (vouchers, merch, etc.)? It looks like Tess doesn't have a pre-made utility to bulk import premiums into constituent records the way it does for attributes, constituencies, and special activities. We definitely don't have the time to manually add these premiums into records. 

Has anyone written custom code for a utility that would add premiums to a list of constituents that they would be willing to share? That or some advice on how to track these kinds of donor benefits?

Thank you in advance!
Maggie
