Addressables bundles management issue

Hello community!

In my project I have levels wich are build of a bunch of textures each. There are some textures used in every level and some textures unique per level. I've configured my remote assets group to build every level as searate asset bundle so build does not take much space on user's device.

Now I'd like to have a separate bundle containing only textures used in all levels to minimize download size when user download new levels but can't find how to configure that. Does anyone achieved this? How?

Thanks in advance.
