Output templates, can I omit some words using $mesh and $textureset?

Does anyone know if in Subtance Painter, for the output maps it is possible to omit some words using $textureSet or $mesh? I mean I always use the name of my materials as MAT_House, I would like that "MAT_" does not appear when exporting or if my mesh is called FBX_House does not appear "FBX_".

Thank you very much.
