IFS Function: Progress to Next Sequence on Undefined Result

[Josh Verran]

I had actually posted this as a Wishlist item, but I thought it might be worth directing as a question in case there's another method I could use.

In my example below, I expected that if the first sequence wasn't satisfied, then it would go to the next.
However, the moment the first sequence is run, it returns the result <Undefined> the next sequence isn't considered.
