Editing efx cues

How does one edit An efx cue and then save it. Record merge and update don't seem to work. I choose the fixtures press suck to get the values back into the efx editor, and then make my edits, but then how do I save the changes back into the cue?

Also are pan and tilt efx linked together. I made a tilt only effect but then when I played it back there were pan efx that I never recorded in the cue? Editing it out proved to be a pain.

Help!

Thanks in advance!
