Thank you, @Jan_Koudijs!
Your method works great! But I think Roon has a bug when using your method. As long as only one version of the album is in the Library, or if multiple versions remain separate entries and are not grouped, then the method works. However, if you group alternate versions, then the method fails. For example, I have a 24/96 version of Diamond Dogs ripped from SACD, and a 16/44.1 version ripped from CD. Track numbers and titles are identical and Roon properly identifies each version. Images below:
The 24/96 FLAC version ungrouped:
The CD version ungrouped:
Group the 2 versions:
This is the result (the CD version suffers the same fate):
Like I said, I think this is a bug in Roon. For individual albums, your method lets me do exactly what I hoped to do. Thanks again!
