How to access exposed variables of a child actor component via details panel?

Yeah what’s up with this feature? I can see entire details panel if I click on child actor inside Blueprint editor, but when I go to Parent Blueprint in level and click on child actor there, it doesn’t exist.

My only solution looks like I have to re-create each variable in parent blueprint, and then cast them to child variable so that when parent variable changes, it also changes child variable.

Seems like a lot of duplicate work for something that could easily just be added to parent’s details panel…
