In the 'Custom Settings Menu' select - Shooting Display - select a1 'Continuous shooting Speed'. Here you can set the 'Continous High-speed' frame rate to either, 10, 12, 15 or 20fps. Once you have set this to 20, you will also see that in the 'i' menu under Release Mode for H
a2 is used to set the maximum shots per burst. E.g. if you want a bracket of 5 different exposures set this to 5.
A1 works as you mentioned. Please be aware the a1 sets the fps for everything, not just bracketing! This is why I have this available in My Menu. To control your bracketing work, use the BKT button on the top (left) of the camera. Best of luck.
