I have a Page inherited from top level Publication, which I should not localize, but at the same time I would like to (somehow) add metadata info to the Page during Page publishing (at that point I can determine what metadata the Page needs) and latter to query Pages on the CD side by that metadata. Something similar to how `RenderedItem` metadata works for deployer/storage except I would need metadata information to be accessible for querying using CD API. Is this possible?
