Hi,
If you want to change the settings on multiple geometry collection assets at the same time, I do recommend using a Utility Blueprint and create a scripted action with it ( so you can then right click on the assets and execute the script to change the properties )
Here you can find a documentation on how to use Utility Blueprint for that purpose
if you want to fracture / cluster geometry collection in similar way then, as suggested above, you can use Dataflow
You can find a quick introduction to dataflow for destruction here
I hope this helps
