More efficient "or" logic?

Is there a way to list similar data in the procedures module using 'and/or' logic more efficiently than whats listed below?

ex.

If {(get block direction = N) or (get block direction = S) or (get block direction = E) or (get block direction = W)}

Then {...}

I'd imagine it would look something like:

If {(get block direction = N, S, E, W)}

Then {...}

But I cant seem to find any sort of nestable 'and/or' functions. Or am I missing something obvious?
