Who knows a prototyping service with page templating and collaboration capabilities?

Question

Layouts and prototypes

I am looking for an online prototyping service for creating website prototypes, I have already familiarized myself with many services, but for the most part they can make primitive layouts for individual pages by linking them to each other, and this can be done in any editor or in the same Google docs. Interested in the possibility of creating page templates, and even better separate blocks, which can then be used on pages. For example, a header, footer, menu or similar blocks are created as separate objects and placed in other pages, and even better in separate page templates. On the basis of these templates, the actual prototypes of the site pages are created. The main thing is that when such a block-object changes, the changes are repeated in all places of the prototype where this block is used. Also interested in the possibility of maintaining a certain database with a description of all objects and blocks: what is the source of data for these blocks, their behavior when interacting with the user, etc. I would also like to be able to comment on individual objects by different people, like Google pictures. Well, for complete happiness, it would be nice to be able to integrate with tasks in the project management system, so that, for example, by clicking on an object in a certain view mode, you could go to the list of tasks associated with this object.
