Combine presets?

I download a preset for a dirty tone I like. I also download a preset for a clean tone that I like. Is there an easy way to combine the two? Until now I’ve been writing down the settings for one and creating a new scene in the other preset manually.

there’s not a very easy way to do it. If it’s for scenes only, what you’re doing is really all you can do between presets.
If you are copying a block from one preset and pasting it into the other, then it’ll paste with the same settings it was copied with from the other preset. You won’t have to adjust settings so much, but that’s the only work it’ll save.
