Can i merge with non-main branch

Can I merge description:
Checks if the specified pacticipant version is compatible with the configured main branch of each of the pacticipants with which it is integrated.

Sometime I going to merge my MR with non-main branch and I want to know about compatible of versions. It would be easy to have some --branch flag for can-i-merge that have 'master' or 'mainBranch' by default but could be override. Currently, I can have kind of the same result with can-i-deploy but it isn't clear and requires an additional stages.
