Request ability to import m3u from various storage paths

I have a NAS with various storage paths defined in Roon. I curated m3u lists created in other programs which have the same storage paths. I just want to import them in Roon, however Roon can’t handle it.

Example:

\NAS1\Music-A
\NAS1\Music-B
etc.

If I place the m3u file in \NAS1\Music-A, it only imports music within this path. It leaves the other paths defined in the m3u file. Other program can handle it (Itunes, etc), but Roon for some reason can’t. When I export a Roon created playlist it exports all the storage paths correctly.
