Can you to get OTA and Cable feed to TIVO

I really want to come back to the Tivo community, but I can't figure out how to get Both OTA and cable signal to the whole house with only one input on the Tivo unit. Sure i could get 2 Tivo's, (BOLT plus and OTA Roamio), but how would i feed them both to the rest of the house. Is it possible to use the minis on 2 different dvrs? Or, is there another way to feed my tivo with both cable and ota.

The reason i want ota is because of the superior picture quality I see over the cables local feeds.

Someone please tell me theres a way to get this done.
