Editing Vray Express Material List - For architects

Hi there guys. I was wondering after have been using Vray for some time and trying to evolve my workflows if anyone could help or guide me to Create my own Express toolbar for architectural use.
Right now im adding / redoing existing materials in Express but it would be nice to name them and creating new thumbnails, groups and maybe my HDRI maps aswell.

If anyone is up for a Co. misson of helping me out with this it would be really nice.
