I am not aware of the fact, that hyperlinks have own identifiers.
What you could od is to construct/create a function, which would read/scan your whole text for some specific words (which are collected inside an ARRAY for example).
All found words in the text, which also are included in your ARRAY, will be converted into a → HYPERLINK <–.
You could use Reg-Ex for this functionality + match() + replace()
Just an idea.
