Full site library import question

This might be a slightly absurd question / there might be something like it shipping with the final GP Premium version, but is there an 'easy' way to install all the GP demo sites in one go? Other than one by one, I mean.

I do quite a lot of initial work on flywheel and there are different parts from each site that I like - and while I have a few of them installed already, I thought I'd try my luck to see if such a one-stop-copy-gp-shop exists :-)
