bradly: did you update your pro to the last version? using 3.4 of PPE

If you did, then you can do it. In 3.4, all aliases alias the type also. For instance if you setup the device TV to be IR and the device VCR to be RF then the button that has
TV-panel-on
VCR-panel-on
will send an IR command to the TV and a RF command to the VCR, no matter where that button is (Home, RF device, IR device....)

so as long as the learning (or UDB code) is not on the home page, you can do it
