Being able to disable exporting Addressables

Hi,
Having seen all of the features that are upcoming (hopefully in Unity 2018.x ), we are very much looking forward to the increased flexibility and efficiency of the new Addressable and ResourceManager API. However, we often have content within our game that we have already packaged up into asset bundles, but do not yet want to ship it with our development builds. Our current workaround is to use a separate "staging" project where we then import the assets via packages - however this requires duplication of lots of content and is inconvenient. Will it be possible to disable exporting of assets marked as addressables but still keep their addressable data?
Cheers,
