I tried creating a flight plan with the fix in it, but you can't go
direct to a fix in a flight plan unless the flight plan is the active
one. For some reason, I found that objectionable when it occured to
me a while back, but now it seems like maybe a good idea. Just create
a flight plan containing all the fixes you might want to use on an
instrument approach, then make that flight plan the active one and use
the waypoint "scan" to quickly select the one you want to use.

The KLN boxes have separate APT, VOR, NDB, INT, USR, and NAV pages.
What I usually do, if I have waypoints of interest that aren't naturally
in my active flight plan, is preload them into their respective navaid
pages. So for example, as I prepare for an approach into KMRY, I would
put I-MRY on the INTersection page. Then, when I'm ready for it
(vectors to the localizer), I spin the big knob to the INT page, and
select -D, OBS.

This allows me to step out of my flight plan temporarily. All it takes
to get back to the flight plan (missed approach?) is to clear the
direct-to operation, then the GPS reorients itself onto the flight plan
route. In many cases, I find this is more effective than trying to add
extraneous waypoints to the active flight plan.
