Management Reporting: Pre-select the Context Selectors at the Slide Level

I learned the appropriate term for our ask here is slide-specific context selectors. We want to select a context selector for a slide, which updates the entire slide's syncing context; yet not have those context selectors sync with the other slides in the presentation. This will enable us to craft our message for a presentation, pre-selecting/configuring which products we need to discuss in a meeting. It will also lower maintenance because currently, I'm having to select the context for each card and text element in the slide. Ideally if we click a link to another page; however, I'd like this context to be reflected in the board or sheet I link to.
