Need RBE opposite

looking for a node that does the opposite as
RBE. I am looking for a node that will only pass if the last two messages are the same.
Does anyone Know of any such NODE?

If just comparing a simple payload then the switch node can do a compare with previous value.

How do i Maintain the previous message?
