Programatic access to 'Path Variables' in Settings

Is it possible for a Plugin to problematically add a new Path Variable setting (i.e. Settings > Appearance and Behavior > Path Variables)?

I'm writing an IDEA plugin for a framework that provides an Eclipse plugin. Right now if I import an existing ellipse project (for this framework) into IDEA, the library definitions have errors since they have unknown path placeholders in them. The Framework uses a standard location on the machine for the libraries. So I know what I need to set these to.


Please see `PathMacros.getInstance()`
