I don't see this option in the Properties area (see my screenshot). I do not want to use the Fade in transition because:
- I want to control the time. The default jumps from 1 second to .28 second - I want something in between
- I do not want to apply the fade to the object that is next to it. I would have to move the object and that is not practical if I have lots of objects to the right.
You can adjust the default length for transitions via the Edit->Preferences dialog but yeah, currently it will try to make the 'spanning' version of transitions when it can. I can see where it would be useful to either have a hotkey to override that while dragging or a preference to create annotations with 'edge' transitions by default.
