The image didn't tell us much more, not showing [or at least not identifying] a "before" situation and an "after." But given the description of your Stretch-one-and-Array-it solution, I wonder whether this is what you're trying to do:

If so, there's a much easier way to do that than your solution. I'm showing them irregularly spaced in the Y direction, which the much easier way can handle the same as if they're regularly spaced, but Stretch-one-and-Array-it would not be able to do since the Array part would only handle equal spacing. And I'm not talking about drawing Lines at the end limits and Extending to them -- those dotted lines represent just "theoretical" or "virtual" targets in the procedure, not drawn objects.
If you're interested in the much easier way, write back.
