I created a grid and then wanted to use that but to modify so I didn't had to retype. Ideally I wanted it in a new tab but I couldn't figure out how so I duplicated the grid and started to modify but when I did that it's affecting the initial grid and changing things there too. 

Can I either move one grid to a separate tab or somehow unlink the grids in the same tab? I don't want to retype everything. 

Thanks everyone who might have an idea.
