Bloom Scene Actions on relationships

I am trying to use Scene Actions to update a relationship property:

I expect that the MATCH works the same way as on nodes.
But if I select and execute it on a relationship I get the error message:
"Sorry, we couldn't find any results for this action., Scene Action could not be completed due to an error."

Any ideas what I am missing here?
