Im guessing there isnt an easy way to do it, but if you vould id really appreciate a half way "skip transitions" that just skips the text boxes going down then sliding back up.
Idk if you can directly edit the the default transition, but if you made your own custom ones, i am pretty sure you could accomplish it by making the setting just redefine them as a transitiom with 0 time.
For me the textbooks dissapearing and re-appearing is just very jarring and annoying - but I dont want to miss any pseudo-animations you may have made using dissolve/etc
