Hi team,

For convenience, especially when scripting, it would be good if the morph command would accept an "id" argument (much like the open command has "id" or combine has "modelId"). This would let the user specify the model id of the coordset created by morph.

Current behavior is that the first available (lowest numerical) id is used, which is not easy to keep track of when scripting.

Cheers,
Alexis

Done.

Added modelId option. If you try to use an existing model id it gives an error.

Added in 1.11 daily build, not in 1.10.
