Secondary sorting

Apologies if this has been asked (and/or answered) in a previous post but I was unable to find a solution.
I am looking to sort items in my collection first by archive (source) and then by date - and various combinations within that. Is secondary sorting (and tertiary, etc) available?

Sorry, but this is not available yet.

We have advanced search and improved string sorting (especially for strings mixed with numeric values) on our agenda – supporting secondary sorting is somewhat contingent on both of these. It’s something we’ll definitely look into when we get to it!

Thank you for replying! - I’m grateful to know that it wasn’t something I was failing to find or figure out, and that its on the agenda!
