Load Level Instance ~ Create Multiple Transformed Instances of the Same Level, not in levels list!

Dear community!
Thank you for this awesome function!
But, can somebody please make another one to unload this levels?
It will be really useful, cause on the moment, there is no simple solution to do unloading.
The function returns “level streaming kismet object reference”.
I think it would be cool to have a way to remove the level by specifying a function on it with this reference.
Thank you for your attention.

P.S. Sorry, for bad English.
