Modify child actor created in construction script?

What I am trying to do is to create a dynamic setup of actors that can be adjusted and edited in edit mode.

For example a TV with it’s speakers. I want to be able to define the number of speakers in the TV blueprint, get them created and then move them into position. If I don’t like the amount, I just change it without altering the position of existing blueprints.

I managed to do this as far as creating the speakers in the construction script of the TV blueprint, which spawns the amount of speakers into the scene.

Whenever I try to select a child actor to move it around, selection is handed back to the TV blueprint, because it has been reconstructed.

How do you handle scripted construction of actors while making them editable in edit time? Maybe the construction script is a bad approach, but I wanted to do this as convenient as possible.
