View Work across multiple Atlassian apps

[Tucker_ Kate]

My company uses several products across the Atlassian suite — primarily Jira Product Discovery (JPD) for product management and requirements tracking, and Jira Software for development work (to make it slightly more complicated we need to track two JIRA projects within different URL bases, but are part of the same company). We also have ad-hoc tasks our team works on that don't fit neatly into either tool that we need to track. Open to suggestions which tool we should track these in. 

What we're trying to achieve is a single, unified view showing all work assigned to each member of our team — across JPD, Jira, and any ad-hoc items — along with the current status of each piece of work, updated automatically so we always have the latest picture.

I've explored building a custom dashboard using the Atlassian REST API to pull this together, but before investing further in that route, I wanted to check:

1. Does Atlassian have a native feature or built-in view that provides this kind of cross-product team overview?
2. Is there a recommended approach within the Atlassian suite for consolidating work visibility across JPD and Jira in one place?
3. Are there any Atlassian Marketplace apps you would recommend for this use case?

I'd imagine this is a fairly common ask from teams using multiple Atlassian products, so I'd welcome any guidance on the intended solution or roadmap for this kind of cross-tool visibility.

Thank you for your help.
