Need help getting auto-linking plugin to differentiate keyword phrases

I’m trying to set specific targets for different variations of keyword phrases that contain the same keyword. Example below:

Ex. 1: Keyword phrase: black cats | Url: http://www.blackcats.com

Ex: 2: Keyword phrase: florida black cats | Url: http://www.blackcats.com/florida

Since the keyword “black cats” is already assigned to a url, when I try to auto-link “florida black cats” the plugin only recognizes “black cats” because it’s already a keyword in the matrix.

The problem lies in using “nested keywords” – that is a keyword within a keyword. I don’t know if that’s the correct term, but it’s the best way I could describe it.

Does anyone know of any solutions for this problem?

Thanks,
Brandon
