Delete all BGP communities except

Hello, Is it possible to delete all BGP communities from prefixes learned from a specific BGP session except ones that start with a given value? For example something like: if (bgp_path ~ 64496) then { bgp_large_community.delete([(!64496, *, *)]); } I haven't tested this syntax, but I can't imagine it would work. I'm mostly curious if there's a concept of "except" when deleting BGP communities.
