Opening a new PDF in a new window not a tab - Architect 8

Hi
With Architect 7 you could change a setting which allowed every PDF opened to open in a new window of its own rather than tabs. You either had it on or off. Bit of a faff but at least you had the option.

With Architect 8 you don't seem to be able to do that and can only have side by side view. I want to be able to see different PDFs at the same time on two different screens so opening in new windows.

I use Architect through work but at home I use Nuance (now sadly obsolete and taken over by Kofax). With Nuance I can just pick up a tab and drag it and it opens in a new window, that is so much more user friendly and would love for Architect to to the same.

Any ideas please? Thank you
