Channel recorded being used in Library Collection smart rule

Hi, it would be handy for organizing some of my library collections if the channel that the program was recorded from could be used as part of a smart rule. The channel recorded is not available to be edited in the metadata, but it does seem like you have a record of it since each recording shows what channel it was recorded from. Thanks.

This works for movies but not for Show collections as shows do not have this metadata, recordings do.
