Disable packs with EA App?

Is there a way to play with a pack for a while and then disable it for a while until you're ready to use it again? With the new EA App or in the game itself?

I would like to buy HSY while it's on sale and play with it in my lesser used save while I wait for the mod I depend on in my main save to update after the patch. But then I don't want to use HSY in my main save for a while because I'm not sending anyone to active high school from the generation that's about to age out of the teen years. I don't want to get spammed with notifications and proms and such until they age up, I just don't want Copperdale to exist in that save until a certain point in my rotations. So is that an option?

I was planning just to wait to buy it until I was ready for it in the main save, but it's on sale, my birthday is coming up, and the older save has a young teen who would be perfect to explore it with.
