Control expiration date for Lead Generation Landing Pages

It makes no sense to program a Landing Page with a default 6 month expiration. What idiot thought this was a good idea.

If I don't want a page to show after a certain date, I can delete it. Makes no sense to have to remember to edit a expiration date. And then if you forget to do it, you're screwed because you can no longer edit the date and the URL is dead.  I have a hard codded URL in one of my software products that no longer works, and no way to get it back. VERY BAD PROGRAMMING. VERY BAD FOR MY BUSINESS.

Please fix this ASAP.
