More R&D Layout options

[WilliamMGary]

This would be a power user feature but I would like to be able to try out different layouts for R&D, instead of the standard connect 3 boxes or all 9 together. I wanted to try to connect 4 for Product A and 5 for Product B.

You can do a 4-5 split manually

But I guess it's good to have more pre-defined layouts in default library.
