EQ per album or even track

[MusicMole]

To counter 'room boom' (or room modes) in the 40Hz area (identified using REW and a UMIK-1 mic) I am using parametric EQ with this line:

stream.options: convOut=-af equalizer=f=40:width_type=q:width=11:g=-17

This seems to be working well and taming the boom on bassy tracks.
The problem is that it is also cutting the bass on tracks that really need more bass rather than less bass e.g. some older classical.

Is there a way to apply EQ to individual albums (folders) or even tracks please?
I'm thinking some kind of text file in the folder which replaces or overrides the stream.options one.

Thank you.

PS MinimServer is excellent.
