Wakeup by Lora Receive on Cubecell

Has anyone been able to wakeup out of low power mode via a lora receive? It doesn’t look like it’s possible as the Lora pins don’t appear to be GPIOs.

If not, has anyone tried to sync multiple disconnected Cubecells to limit collisions? Using GPS time would be OK, but sync’ing with wakeup times looks tricky.

Thanks.
