How you change the download frequency for a single Podcast?

I have iTunes 11.1.5 for Mac, and I can't find how to change the down load frequence , aka "check for new episodes" setting for individual podcasts. I've tried using the settings menu in the "My Podcasts" and the "List" podcast view. When I do this, I see these setting:

• Keep
• Download
• Sort Order
• Play Order

If I click on the "Defaults..." button, the top setting is "check for new episodes"

I have no problem with being able to change the default download frequency setting, but I am at wit's end with locating where I can change that setting for individual podcasts.
