Just only discovered this little utility inside Poser, will change geometry references from absolute paths to external runtimes, into relative paths that in the main runtime - which in my specific situation, is what I want exactly.

It will fix cr2,pz3 and pp2 files. 

At your Poser menu bar, click Scripts, and when the drop-down menu appears, select GeoMods, then Checkpaths.
