Tempo changes. Fl studio

Hello, I got a question about tempo changes.
Its easy to change tempo whit automation clips but it restreches everything.

If i only want to restretch my drum beat how would i be able to do that (FL studio).
So that only my drums go faster not the sounds on it. It sounds terrible when it restreches all

Sorry for my bad english!

Render all drum parts to wave , new project do your automation of main tempo , render down off master then use that wave with actual track ??

^ that is a good beginning
But what I would do is bounce the drums, put those in your project, and just stretch those to the wished length.
