[Feature Request] Fade / Slide transitions between [all] selected frames

[ImagineerNL]

Is your feature request related to a problem? Please describe.
Currently the Fade or Slide transition only applies to the current selected frame and the next unselected frame.
If you select multiple frames, it only applies the transition from the last selected frame to the next unselected frame.
This is frustrating when you have created multiple 'slides' for a presentation and want them all to transition into the next slide, as this requires you to manually select each frame and fade/slide them to the next. rinse and repeat.

Describe the solution you'd like
It would be great if the fade/slide effect would be applied between each following frame of the ones you have selected.
If you have 2 frames selected, it applies same as current.
if you have 3 (or more) frames selected, it applies a fade/slide between 1 and 2, 2 and 3, etc.

Describe alternatives you've considered
Alternate solution: doing this manually frame by frame, or selecting a whole different application to create videos.
