Can i download OBB not on install, but when i want?

I create a game, and want to download some level when player want play them, no when he download apk. Whether it's possible to don't download it on start, but when user want it? I want to pop up, that "Do you want download additional content"

 

Thank you, but that solution involve a server to host Bundles. With 100k new users every day it is a little bit cost. But if its no other way...
