Hi @shahidt,
Thank you for sharing your use case!
Currently, there isn’t a built-in way to dynamically generate and embed shareable links into TextBlocks within a Canvas Dashboard. However, I believe the Upcoming: Tabs in Canvas Dashboard 
could be a great solution for your needs.
With Tabs, you can consolidate your three interrelated reports into separate tabs within the same dashboard. You can then create a single shareable link for that dashboard while applying permission settings to filter data by client. This way, users can seamlessly navigate between the reports without needing manually generated dynamic links.
Since we’re actively developing this feature, we’d love to hear any additional requirements you might have for Tabs. Let us know if there’s anything specific you’d like to see!
