Not easily is the simple reply !! Roon is basically album based and ID is really centered around albums so singles etc just don’t fit and will probably remain unID’ed
One thing I do may be of interest , I have a NUC/ROCK with an internal 4Tb SSD and an external USB HDD. (this is my “Non Core Library”, duplicates , stuff I am unlikely to listen any time soon but don’t want to lose etc)
I have set Roon loose analyzing both , then I disable the USB drive. in Settings > Storage
The SSD now becomes the main library , and Enabling the USB Drive adds all the files within a few minutes , the analysis is already done so no whirring circle top right
When you have had your nostalgia , just disable it again.
This drops the size of my library by about a third and I think speeds things up and certainly declutters the views. Inevitably I am loathed to delete albums and tracks so this keeps the Core library looking neat
Check out the “Various Artist Thread” for a few pointers
Just a thought
