Displaying the same album across multiple box sets

[simbun]

I was going to go down the route of asking to support m-TAGS (http://www.m-tags.org/Overview.html) which would solve all the complexities of having a different navigation and storage philosophy, but I see this was asked back in 2015, so I was just curious on your thoughts of:

- processing album groupings after .displayFormat
- implementing a coalesce function in the display formatting

I had to ask :-)

Thanks anyway
