Wblock transfer between Acad and BricsCAD

Hello

I have a idea for copy/paste function to transfer between AutoCAD and BricsCAD faster than command typing Wblocks.
It is based on the idea of SUPERCLIP.LSP Super clip command (c)2001, Justin D. Andrews
The main obstacle is the difference in location stored in "ROAMABLEROOTPREFIX" which it uses

AutoCAD
C:\Users..\AppData\Roaming\Autodesk\AutoCAD 2018\R22.0\enu\

BricsCAD
C:\Users..\AppData\Roaming\Bricsys\BricsCAD\V20x64\en_US\

So What is needed here is a LISP call and a directory location for a "combined and global folder" so that can work on anyone's machine from any location.
Any idea's how to pull this of?
