The descent profile for managed descent is based on the track miles remaining from whats programmed in the box. So having CPT-POMAX-BRI-procedural ILS will have a lot more track miles than you can actually expect and hence a rubbish descent profile, as 99 times out of 100 you will get something that approximates to CPT-POMAX-CF27. The BRI will be tuned on the ADF so if on getting to POMAX there are no further instructions (ie radar vectors, which is almost 110% guaranteed) then it's pretty easy to track the needle.

As I said it's very easy to add the BRI if needed (just press DIR then type BRI, or insert BRI as TO waypoint).
