Hi all,
Sorry I haven’t got to this sooner, I have been exceptionally busy. With that said, I have updated the nodes in this thread in the thread below to handle multiple sheets - raised by @Kotey.Nikoi
There is a new preview node too so you can visualize all the sheets and view locations easily (it creates a tiled array in the Dynamo viewport - handles multiple sheet sizes too).
Move on over to the thread in this post for any new updates/comments as I think this thread has got to it’s end. 
Cheers,
Dan
