Show Asset Bundle list before downloading any content

Hi,
I must admit that I'm new to the unity asset bundle system. I'd like to create an in-game browser where
the user can browse through available asset bundles and decide which one to download before it actually gets downloaded into the game.

I know how to create asset bundles and to load them all into my game when it starts. However I'm not able to generate some kind of life-updated "item-table" which contains all avaliable asset bundles on my server, so that the user can desicde by himself which one to download by just clicking on one of them.

Is there any way how the user gets an overview of all available asset bundles before downloading them anctually?
