Default arc settings

Hello everyone.

Can anybody tell me how to change the default behaviour when I draw an arc?

I want to write "arc" in the command line, and start drawing it by its center first, then its start point, and I finally the end one. I don't want the default 3 points method.

I do this faster drawing circles and trimming them, than selecting the suboptions of the arc (center, start, etc.). It should not be  XD

Thanks!!
