Hi Tom!
It looks more cumbersome than it is in practice. You can use C-c C-l to
add the link and depending on the length of the link type name, it can
be very close to the same number of keystrokes you'd need for
\enquote{}.
During normal LaTex editing I never type `\enquote{}'. Of course I type
" and AucTeX automatically inserts `\enquote{' at the beginning of a
word and `}' at the end of a word, depending on whether `csquotes' is
loaded or not.
Apparently someone tried a simple hack:

When I find the time I will try this...
Thanks & Regards.
