import session markers ("Bereichsmarker") from WAV into Multitrack

I’ve inserted two WAV files directly next to each other on the first track of a multitrack file (two recordings of a single concert, one before and one after the intermission...). I’ve already added section markers with song titles to the WAV files. I’d like to carry these section markers over to the multitrack file. No problem transferring the markers from the first clip, e.g., via CSV. However, I can’t insert the markers from the second file starting from their position because they’re always inserted as absolute markers, which overwrites the markers from the preceding first file. No way to do this, right?
