SuperPutty like Window support

I'm considering migrating to your RDM product. I've historically leveraged both mRemoteNG and SuperPutty.
I'm trying to find a single replacement for both.
Your product is the closest I've found. Except the SSH Window handling in the free version is quite poor. There seems to be no option to have more than one managed SSH session on the screen at the same time. That is very wasteful. No I'm talking about having multiple detached un-managed windows. That would just be clunky.
Please see this tutorial for how SuperPutty does it: https://www.puttygen.com/superputty

Is this a paid only feature I can't see? Am I simply missing the option? If not is it on the roadmap or could it be?
