Is there a way to change the OSX Bluetooth ID that is used by external Bluetooth devices during automatic paring?

I run 2 or more OSX installations on separate MacBook partitions. Devices do not automatically re-connect again if a device is paired with partition 1 and partition 2 boots up and tries to connect. I need to manually unpair the device in OSX and then re-pair it. Seems this could be avoided by changing the MAC address in the OS
