pack uv without rescaling

Hi,
So I have floor boards UVs done and scaled how I like them…

Is there a way to move them all to a single UV tile(I don’t mind overlapping) I need to do that so that a single floorboard doesn’t show texture seam…


Another question, say I have multiple wood textures/variations of the same type and want to randomly distribute them per board in material so that I get realistic board variation… How to do that using cycles materials?

Thank you very much!
