Displaying the same album across multiple box sets

[simbun]

As much as I'd like it to look nice in the UI I wouldn't want that to be at the expense of the tags themselves.

Having given up on the idea that I could get this displayed the way I want I went down the route of displaying the album twice by changing the Album via MinimServer using a tagFormat of Album.displayFormat={$album^$boxtitle^ (^)} but this displays as a single album with concatenated Box set names [A Hard Day's Night (The Beatles, The Beatles in Mono) ], at which point the tracks are intermixed when you drill through.

Finally I tried a tagValue of Album.merge={boxtitle}, but this gives me errors for all the tracks in the album

Looks like I may need a little more reading around this as I was hoping that I'd simply be able to change the value of the album tag using the pre-processing and MinimServer would treat it as though it WAS the album tag.
