Editor widget BP - can I auto populate a combobox from actors of class?

Hi guys, I have virtually no experience with UMG and don’t know if what I want to do is possible in blueprints. I’m creating an Editor Widget BP, in which Id like to have a combo box (or other suitable thingy) that has a list of all actors of class. I’d like to be able to have the combo box be auto populated with the items in said class, so my end user doesn’t have to go looking for them. Much like it would appear if calling a function in editor sort of thing.

Is there an easy way to do this? Did I explain what I’m hoping to be able to clearly?

I thought this might work, but it seems I’m missing something.

I have since learned not to use a variable for the class if the ‘get all actors…’ node.
