Converting a hierarchical group of static meshes into a blueprint?

Currently i have a object consisting of many static meshes (that are also parented to eachother) in my scene.
However in order to drive this object i have to put this collection in Blueprint.

The problem is that when i use “Convert Selected Components to blueprint class” i lose all Hierarchy/parenting.
Normally this would be an easy fix of dragging the objects back into their intended structure, however, in this situation i have a collection of 440 static mesh actors that need to be converted while maintaining the hierarchy.

Is there a way to do this without losing all structure information?

Did you try to make a group (Ctrl + G) from hierarchical group of static meshes and than create a Blueprint?

tried that and the basic parenting, and both had little effect.

Did you find the solution?
