Sequence with manual flats

I have a sequence with a “flats” target followed by a “lights” target. The lights are postponed until 9:30 pm when the moon settles. I started the sequence at 8:00, did the flats and left the garden and went into the house. At 9:30 a message popped up to “remove the flat box” and the sequence got stuck there.

-> Is it possible to show that message at the end of the flats target and not at the beginning of the lights target? (I know I can setup messages manually. But I’m talking about the message that pops up automatically when using the manual flat box.)

-> Is it possible to start the autoguider after the flats target? When fiddling around with my flats box I often loose the guide star.
