Search for instances of a specific BP node in project?

Is there any way to search the project for instances of a particular BP node?

The project contains many hundreds of Blueprints and I want to find all the Blueprints that use a particular BP node in their Event Graph, just as I might search the codebase for references to a particular function.

That is one feature that blueprints really lack compared to good ol C++. Search function in blueprints is terrible. For me this is most limiting factor for making pure BP projects, at certains size there is no hope to find such things.

Well, if you try to delete the blueprint?

Anyway, you can search on all blueprints IIRC per string

Could one expose a custom BP node that makes a list of all the references?

Can’t you just open a blueprint and search, with “Find In Current Blueprint Only” un-checked?
