Default LM/LK question

I was thinking about this a few days back, and realized I didn't have a
clue about how a particular aspect of ascending from the surface of the
Moon back into orbit for the docking with the Apollo CSM or Soviet LOK
was handled.
Once landed, the LM or LK could lift off into lunar orbit in pretty much
any orbital inclination due to the low rotational rate of the Moon.
So how was the correct orbital inclination for liftoff determined?
Land on the Moon with your spacecraft facing 5 degrees from its intended
directional bearing in regard to what you can see out of its windows in
a N-S-E-W direction, and unless you adjust something it will ascend into
a orbit that's 5 degrees off of what was intended...which may exceed the
ability of the CSM or LOK to change its orbital inclination to
rendezvous with you.
So, once landed, did you adjust something to get the guidance system
aligned with your intended ascent trajectory in a horizontal bearing
sense to make sure you were heading for the right orbital inclination on
liftoff?
