Is it possible to group objects?

What I mean is lets say if I were to create a door using 5 objects is there any way of my grouping it all together and creating 1 object out of the 5 that I previously had so basically whenever I want the prop I can just select it instead of me having to create the door using 5 objects all over again, I really hope I explained it well so you can understand. If there a possible way of doing it please give me the steps cause I’m new to this. Thanks for your time.

Yes to create a group in the viewport with the objects selected press Ctrl+G and it will create a group comprising of the selected objects.

This does not work… all is well until I add NEW MOVEMENT TRACK in Matinee all of the objects jump together…and they are grouped. What am I missing here?

A little more info is that it is a door with many parts and they are grouped but when I add NEW MOVEMENT TRACK in Matinee all of the objects jump together

Is there any way to ungroup objects?
