Description:
Suppose I have some objects, like a text frame, a formula and a picture. I want to make them disappear in the same way and at the same time.
I can select all of them and add the animation, by clicking the "+" button in the animation window. Unfortunately, I cannot change the default category "Entrance", as well as the effects and delay (and other options besides the "Start" option).
I remember I could do this in a previous version of Libreoffice Impress. 
Changing the objects animations one by one is really annoying, please try to change this...
Thank you for your availability.

Steps to Reproduce:
1.Create some objects, like a text frame, a formula and an imported picture.
2.Select them all and add an animation for the group.
3.Try to change the category from "Entrance" to other, or change the effect to assign a common one.

Actual Results:
You cannot change the category or effect or delay to be assigned to all the selected objects.

Expected Results:
Give be the possibility to add the same animation to a specific group of  objects.


Reproducible: Always
