Another point on this. As I recall, there is no way to cancel the AH Warning window, although it can be drug to a mostly off screen location.. While the previously mentioned ability to calibrate from the AH Warning window, it would be a nice option to be able to close the window. Perhaps disable the EFIS window for as long as the AHRS is deemed to be out of whack as well. I know I've had situations where the AHRS was, for whatever reason, not calibrated, I was VMC, didn't need the AHRS/EFIS, and the AH warning window was a distraction that I didn't need on climbout from the runway, or for the rest of the short flight..
