How can I select which iPhone my mac will select to place cellular calls?

Question

Hi,
I have two iPhones connected to my Apple ID with lines from two countries as I travel often. When I receive calls on any of those, I can pick up the call from my mac. But when I want to make a call from the address book on the mac for example, then the call goes through the line that was selected by FaceTime on my Mac. It does not seem to matter which phone is on, on, the other or both, or which physical iPhone I use: what seems to matter is the simcard, i.e. the calls always go through the same number. I would need to be able to select which line I use depending on where I am. I tried signing off FaceTime on both phones and mac to no avail. When I turn them back on, in whichever order, FaceTime always picks the same one (and shows this as the Caller ID that will be displayed in the Mac FaceTime preferences...
Ideally, I should be able to select the line in the same way I can select which caller ID I want to start conversations in FaceTime or iMessage but thus does not seem to be implemented. yet?

Have you tried changing the caller id on FaceTime on your Mac to see if it picks the other phone?  Seems to me that what you'll have to do is change the caller id each time you want to make a call from each phone.
