Oh you don't multiple updates. You can just make a lot of them and then, when you're done, send all of them on one sheet. This would avoid multiple updates. Also, the final result would be more impressive. 

I do plan on making a few more, which I haven't made yet, so putting them on a sheet would require mulitple avoidable updates. I will put them all together when I'm done, though.

Maybe you could put all of those on the same sheet ? Looks cool either way.
