Cheers Guys,
The Align view to active selected function (Shift + numpad) is probably my safest bet for now.
Perhaps if what I’m thinking of doesn’t exist (even after a google search for addons) then it’s possible that it’s not necessary in the Blender workflow.
That being said, this might be what I am thinking of. This could also come down to me learning relevant terminology to know what to google for etc etc. https://blenderartists.org/t/align-3d-view-to-custom-transform-orientation/1328947 included in that link is this DL link – https://github.com/fdaubine/Align2Custom?tab=readme-ov-file
I’ll have a look and let you know if it answered my Q!
