Linking to specific Tabs / Accordion panels within a page

[RussellPlayer]

I have a canvas page that contain Accordions as well as Expanders and Tabs...

I am hoping to use links from the calendar that take the student directly to the appropriate Tab rather than just the top of the page.
Ironically I did get this to work late last year, but can't find the file/page in which I did it.

I'm pretty sure I used ID tags to name the tabs, but can't remember how I then referred to them within the link...

Any help would be much appreciated!
