Pair multiple remotes to same Roamio

Is it possible to pair two remotes to the same Roamio? One of the remotes is the original slide remote (not pro), the other is the remote that came with the Roamio. I have the slide remote working in IR mode, but I haven't found conclusive information if it is possible to pair it in RF mode, without losing the pairing on the first remote. (I tried to pair it following the instructions I did find but it did't work.)



Thanks.
