Cucumber: Testing multiple different multi-line scenarios with a single scenario outline

Question

So, I'm writing a tool, that, as one of its core features, needs to be able to ingest a specific vertical-bar delimited format. I'm using cucumber, and I want to be able to have a Scenario saying "If the file doesn't have this, then it should reject the file." The trick is that there's a couple ways to "not have this", and each way requires a different multi-line string. Is there an easy way to list a couple multiline strings in a Scenarios table, or the like, or am I stuck with having repetitious scenarios?
