Displaying selected list content based on other selected list content

On your idea about using a new section for a list, because we're using two lists sort of... I guess you could call it nested, I'm guessing this would require giving them the ability to add new lists, or rather, in this case, sections.

For example, it's easy for them to add a new record to an existing section. So, adding a new carrier, say GHI, to the carrier list would be just adding a new record.

However, they would then need to be able to add a new section for GHI in order to list out the plans GHI has... like Federal Employees, Medicaid HMO, etc.

I do like the concept behind this and definitely want to find out more for future use, and, if I had a lot more time, I could try talking someone into implementing it right off the bat, but I have a feeling this will be something to add later, since putting it in may require more coding that we just don't have the schedule for at the moment. We're already quite a bit behind schedule on delivery.
