About the transition view in Qt Design Studio

It seems this view is very underdeveloped or am I missing something?

For example, I can't seem to select multiple properties at once. Is there no way to apply the same easing curve to multiple properties easily?

And the the draggable blue bars don't seem to have any sanapping to align the duration of multiple properties
