How to style a command in a ScriptEditor (.rhproj) project

I’d like to be able to set the CommandStyleAttribute on commands added to a project in the ScriptEditor. Specifically, I want to make sure that one of the commands in my project is set to DoNotRepeat, but I can’t seem to figure out if this is possible, and if so, how to do it.

If this is something where I need to explicitly create a Command, with all the nuts and bolts, that’s fine, I’m just not sure how to do that in conjunction with a ScriptEditor project, either.

Any help is appreciated.
