Hi Matt,

As mentioned by Ihor, you’ll want to take a look at the curent version of
ox-latex, specifically `org-latex-src-block--custom' which now contains `(?c .
,caption)'. You may want to consider modifying `org-latex--caption/label-string' to
accept the form `(element info &optional content-only)' or reimplementing just the
bits needed for this purpose — which ever works out nicer. Looking at
`org-latex--caption/label-string' a substring approach looks quite fragile, though
you might be able to get away with an application of `replace-regexp-in-string',
though I’d personally consider this a bit of a last resort.

All the best,
