Hi, currently not. I will make a ticket for that.
Your ticket: "Command Remap #69"
Unfortunately StreamDraws never took off (9 Sales in total as of time of writing, that will never make back the development time put into it) and is currently not longer in active development. This feature would be also not too hard to program in.
So it goes definitely to the list.
Do you have a particular problem with the current commands?
What would you like to re-map? Maybe I could code it hard in if its good for everyone (this would be so quick to do I could actually do it in a reasonable amount of time ^^).
