Melodyne Transpose on an already created Region Effect?

Hi. Sorry if I missed it here somewhere, but I have a 3 part vocal harmony on three tracks, all going to one bus. 

I tuned the vocals by creating a region effect with Melodyne and all is well.

Now, I'm trying to transpose those vocals up a half step but can't figure out how to use Melodyne on them again to do this.

My workaround was to export the three vocal tracks to one wave file, put that on another track and then I created a region effect using Melodyne and transposed it up.

The problem is that it's now uneditable should I want to make changes in volume/panning/effects, I'd have to start the process over again.

I'm hoping there's an easier, more direct way to accomplish this. Wait....

As I'm typing this (I'm not near my music computer to try this), I'm thinking "WAS" there a way to just take the individual vocal tracks one at a time in Melodyne and maybe choose Edit Region Effect? And pitch them up from there and just save this as a new Project? I feel dumb now as I'm guessing that's all I have to do. Can anybody confirm this.

Thanks.
