A-Flex+Ramp=Screwed? :(

For all of its butt ugliness, that "EPR Ramp Only" feature on the Elite S8 was very nice! I am lost as to why Phillips did not add it to the PRS1?

The best I have been able to find is split night mode. If I had my way, it would be 30 or at most 60 minutes, but it seems the least I can do is 120? And no APAP option on the first part of split night?

Has anyone found a way around this? Found a way to have the C-Flex or A-Flex ramp only or APAP during the first part of split night? It would be nice to be able to have the A-Flex when one goes to sleep and then have it turn off. But it seems difficult to do on PRS1. I am sure the S9 has it, but I don't have an S9.
