So no way to update firmware while rooted on P9P?

So since the firmware updates are not 'flashable' yet via TWRP, am I right in assuming that one can only update one's firmware if one goes back to stock?? I know this will change but trying to understand the current options for flashing/installing firmware updates for the P9Plus (rooted), thanks
