Mosolov's Missing!

I use AllMusic to get canonical names of compositions. Recently, I acquired an album that contained two major works by Alexander Mosolov: Harp Concerto and Symphony no. 5. Neither appear in AllMusic, methinks because they are noted on the album to be premier recordings although they were written in 1939 and 1965. Roon does not recognize them.

Anyway, this omission should be corrected. Can Roon do this, or can you tell me who to contact? Thanks.
