You can do this:

Merge "yourmesh.msh"; // load your mesh
Delete Physicals; // delete the existing physicals
Physical Surface(1) = {xxx}; // define new physical
Physical Surface(2) = {xxx}; // define new physical

Then export as STL, which will only save the new physical surfaces.

Note that at the moment you cannot export *volumes* in STL format, only 
surfaces. Are volumes part of the STL spec??
