Editing level blueprint variables

Is there a way to edit level blueprint variables? You know, how, with a class blueprint, the variables show up under the properties of the class blueprint in a list, and you can change their values. Is there an equivalent list for level blueprints? Thanks.

I have the same question. Any ideas?

Not really.
A Level Blueprint is a unique instance of the LevelScriptActor Class.
You can create a C++ class that extends LevelScriptActor and add your variables to it and set your Level Blueprint Class in the Project Settings to your new Class.
However, these Variables are then in every level blueprint of your project.

There is no possibility to get the Level Blueprint in a Blueprint. You need C++ for that.
