2 x SZ100 Controller Cluster - How to assign AP's to Specific Controller

[robert_lowe_722]

Hi All, Have a 2 x SZ cluster where i would like them to work in more of an active/standby mode than an active/active scenario. Even if i reboot a controller to force all AP's over to the other, over time they will disperse over the cluster. 

Is there a way to tell an AP or a Zone to prioritise one controller over another? I've had a look around but cant see anything.
