Mod to stop Sims watching other Sims slow dance

Hello :)

I hope somebody will understand my question. I will try to translate it in english as best as I can.

Slow dancing came with My Wedding Stories. But this dance overrides interactions between other Sims like the Sweetheart dance from High School Years.
When Sims are in one room and some teenagers are dancing the Sweetheart Dance from High School Years, and another pair is doing the Slow dance from my Wedding Stories, everyone stops the Sweetheart dance to watch the Slow Dance.

But I want everyone to keep dancing, no matter if they are slow dancing or if they are sweetheart dancing. I want to have more variety at my partys, not everyone dancing exactly the same.

So is there a way to remove the forced watching Slow Dance from My Wedding Stories?

Notice, I've never before made a mod myself, so please consider that I am a dummie in this area. :p If you explain something to me, then please do it dummie-proof. XD
I would be very thankful if someone who has knowledge in modding could help me out. :)

Have a nice day wherever you are in the world.
