iTunes Match question/multiple library

Ok, I know how to create multiple libraries. However right now, I have match turned on. It has synced up my whole personal library. However I need to now add several thousand new songs to my library. It's my DJing library, which is all clean versions. I don't want to match all of these, especially since i'm importing at a higher bitrate, and I do not want to go over the 25k limit. Is there a way to have 2 separate libraries viewable by itunes at once? But have only 1 of them matched? Hopefully this makes sense...
