Option for "model name" in metadata

[miasik]

For now SM loads a merged model as a something like this:
Model: "XXXX + (YYYY - ZZZZ) x alpha (0.5,0.9,0.74,0.58,0.42,0.26,0.1,0.1,0.26,0.42,0.58,0.74,0.9,0.5,0.9,0.74,0.58,0.42,0.26,0.1,0.1,0.26,0.42,0.58,0.74,0.9)_trainDifference"
and the same information gets saved into generated images then I run generating with the loaded merge. It could be useful, but the name doesn't contain any more important information such as elementals.
Please, add an option to have the "Model:" field as just its merge ID.
