Question about level streaming(possible bug)

ok so ive looked all over and have looked at the content example. and im cant seem to figure out how to associate a level with a streaming volume from what i can see there is suppose to be a set level option when you have a volume selected but i cant seem to get it to show. ive right clicked the volume and i have right clicked the level im trying to associate with the volume and there dosent seem to be any option to add the level to the volume it self with out the need of blueprint. which in my case i cant use since that requires triggers .

after a bit more searching through the hub here i found the answer and this should be added to documentation about the level details panel in the level panel since its not really well seen or even hints to being able to set your volumes thereā€¦

I have the same problem, what is the solution?
