Unfortunately no. The macro stepper requires macros to fully expand before it can let you step through them.
You can, however, use this `obs.rkt` file (attached) to debug macros as they are expanding, and will print the current expanding syntax to stdout. While not the most convenient thing in the world, I have been able to use it to debug some pretty large and hairy macros. (Thanks to Michael Ballentyne for giving me the original script.)
