How to get the streaming level of an actor in Blutility in editor?

This code will output something similar to /Game/environments/envName/Levels/envName_v001/subLevels/LSL_envName_V001.LSL_envName_V001:PersistentLevel.SphereReflectionCapture_1

To move actors to a level, you just want the LSL_envName_V001 bit.
