When groups are created via a PS Tool, automatically apply a name to them. The objective is to make Entity Info more descriptive and Outliner more usable (for instance, if you want to manually find a specific element of the model and hide it, it would be easier to find versus randomly clicking and expand unnamed groups). The names could be the same or similar to their TAG((Layer), but subgroups may need to be more definitive. Also a group may have a TAG (Layer) designation of "Untagged".
See the attached model, make sure Entity Info and the Outliner are open.
In the Outliner expand individual groups (also do an expand all) then see if finding a specific group or types of similar groups is easier.
I admit the names I applied may need correcting or improved.
