Suppress Sections/Collections on Dashboards

I would like my users to be able to suppress certain cards or collection of cards prior to exporting pages.

Some times the users want more details for certain clients, and instead of having multiple pages, some with less cards, and some with more, I thought it would be great if they could just filter on sections, that would actually remove those cards before exporting. Maybe you can filter by Tags? Or by Collection Name? It would need to work on Story pages!!

Currently I duplicated the page, and have one page with all the cards, and one page with specific sections removed, but feel there should be a better way, as this just creates too many pages, that just confuses users as to what page they need or want.
