E2Studio Debug on 2 different boards at same time, separate instances of E2S


I'm using E2studio v7.8

I have 2 boards with different RX65n devices. The two projects open at the same time in separate instances of E2Studio. Connected to one is a E1 and the other an E2 Lite.

Should it be possible to debug both at the same time?

At present I'm finding which ever I start debugging second stops the other debugging session.
