CLI command for renaming texture layers

Hi,

I was wondering if there is a CLI command that lets me rename a texture layer? I could not find any and have to resort to the default names.

For context:
I am running RC from the command line and sometimes need to run two texturing steps and need to check if there is already a texture on the mesh. It would be nice to do this with an explicit name, as there order in which I generate the different texutres is not set.

Best
