Webrequest for addressables

Hi

I'm trying to find a way to customize the webrequest used by the addressable system to get the bundles.
Currently I know how to use signed url to enable the usage of tokens. But there is a way to set how the assetbundle is retrieved from the remote?
All I can see sniffing around the addressable package are provider using directly assetbundle.get() functions, which would mean I should create providers using UnityWebRequestAssetBundle.GetAssetBundle and then I can personalize it.

Is that right? What would you suggest to do? I try to suggest way that steer clear of anything that deal directly with assetbundle and this seem a bit of a hack.

Thanks for any thoughts!
