Salut Christophe ! The latest nightly snapshots should load multiple stl 
faces and tag them separately. Let us know if this doesn't work.

Gmsh will not remesh these faces, though. It's something we will 
reintroduce at some point, but the remesher is not ready yet.

Yes, you should be able to do it: I use 6.3.0 on my own machine.

We need to update the automatic build machines to 6.3.0, but this will 
take some time as 6.3.0 does not work with g++ on Windows (it requires 
Visual C++).
