loading up a folder filepath for abstractions not in filepath preferences

I have a patch that contains oodles of abstractions and I want to keep them nice and neat in a subfolder. I dont want to have this folder's path defined in the Max File Preferences menu, since i want the editable main patch in the main folder along everything else to be easily moved around. So far I can only come up with the below, which loadbangs thispatcher to somehow define the folder that loads up the abstractions, regardless of where the parent folder resides...

Any thoughts, ideas? Cheers, r
