Automatically group windows when they are opened back again

Hi, I'm finding this program very handy to manage multiple windows when trading (you might a have a niche there if you don't already).

I'm using it with Sierra Chart and it works fine, except when I switch from one chartbook (a group of windows from Sierra Chart) to another and back, the Groupy saved group doesn't seem to be working:

- group 3 charts (windows) together

- switch chartbook back and forth (this deletes the previous 3 windows and creates them back again)

- the windows with the exact same title are created by Sierra Chart but seems they have different internal  Ids or something and Groupy does not group them back again.

ps:

I've been looking at the .groupy file and having an option to set a RegExp (I'm a developer) or similar so I can tell Groupy how to match the windows when they come back again would be soo useful.
