Overnight Pull-Up style training pants for toddlers and preschoolers

We love your training pants and would love to see a more absorbant "overnight" option available, especially in larger sizes. My 4 year old still needs overnight protection, but the training pants need to be very absorbent if they are to work for him. I know of many special-needs families who have kids into elementary school who still need training pants, so i know there would be a market (similar to "Good Nights" or "Pull-Ups Overnights")
