Is this what you are looking for?
(I read your post as wanting to start a sequence (or the night's run) with your focuser at a particular point....)
In focuser control:
.....The Other button brings up a special menu seen below:
Controls:
Set absolute focus position for first filter use: Checking this option will cause the focuser to move to the absolute focus position set for that filter. The filter change can be for anything (the first event, AF override filter, Plate Solve override filter, etc.). Whatever filter is set first will cause the absolute position of that filter to be set. This is most often used with the "adjust focus per filter" option and it is important to note that the first (and only first) filter change will not behave in the way that all subsequent filter changes will behave. Normally, the focuser only moves by an amount equal to the difference between the old and new filters focus positions (the delta). Checking this option will not use any delta, but set an absolute position. This is useful if your first filter change will be for AF override and it will move the focuser to a point (regardless of temperature) where AF can succeed.
Unsure if the above works when you are not using a filter wheel....but you may have got over that part already with how you appear to have set things up. It may be worth a try....that is....check the "Set absolute focus position for first filter use"
