Blueprint mesh hierarchy level instances

I have blueprint hierarchy of excavator mesh (for example): cockpit (parent), bucket holder (child), excavator bucket (child);
Hierarchy made directly in blueprint via arrows dummies.

I need (No scripts, no events. Just in level viewport different states):

  • first instance placed in level (by
    hands) - unfolded excavator bucket
    position/rotation; second instance -
    folded excavator bucket; third…
  • first instance looks like complete
    hierarchy: cockpit - bucket holder -
    excavator bucket; second instance:
    excavator bucket - disabled

I don’t understand how to do this. All instances always repeat each other. How to ‘break links’?

Thank you very much friend!
