Is there a plugin that provides editor functionality to directly set the value of an Attribute in the Gameplay Ability System?

I’m making a game with the Gameplay Ability System and many of the character’s stats are organized as Attribute.

For game testing and balancing, I would like to be able to easily and directly set the values of the Attribute.

Before I create this feature myself, I’m looking to see if anyone else has encountered this situation.
If you know of a plugin that does this, please help me out.
(It seems to be a real pain to search Fab for products with this particular feature).
