Groupin + Animation is buggy

Using Impress from "LibreOffice 7.2.2.2 20(Build:2)" here

I have a slide with several images I want to animate (appear one after the other)

3 Scenarios, 2 failing, 1 working but is not what I want:

- [cf. Attached slide1] If I insert the images, then group them, then enter the group and create the animations => I get a slide in which the whole group appears in a single animation, whereas the animation tab clearly shows multiple animations of singlely identified objects.

- [cf. Attached slide2] If I insert the images, configure my animations, then group the elements together (eg. to move/resize them as a bunch), the grouping just *deletes* (without warning!!!) the animations. Worse : if I hit CTRL-z, then animations come back, but with "-1" as the object identifiers, thus are totally non functional! And the same final result as slide1 : the whole group appears at once.

- [cf. Attached slide3] If I do not use groups, animations work as expected, but this is not what I want ! I want (i) to group the individual images, because they are *semantically* related (parts of a big picture) and I want to manipulate this semantic object on its own (resize/move the big picture without loosing the relative positions/sizes of the individual elements) ; (ii) to animate the individual (sub)images.

In theory my need should be easy to fullfil in Impress if: (i) animations would refer to individual objects ids (ii) groups would have their individual id.
PROBLEM: it seems grouping messes with ids and/or that animation are not attached to individual object IDs...
