Activate 2D on the ground. Rotate the plane until all surfaces are neutralized. Now yaw the plane in the direction of the bank, changing nothing else. I think you will find the Guardian will adjust the roll as necessary to hold the heading. Haven't tried it.
You might better achieve your goal by setting 2D level and adding a trim offset to the ailerons when the switch is in 2D. Guardian should interpret this as as a command to continuously change heading, causing a circle. Haven't tried this either. The same technique should work to establish a climb with the Guardian set for level flight. This might be easier to adjust.
