Is there any way to have a field on a user profile that allows the user to add more than one value and have them displayed in a list? For example, a set of "education" fields that the user can add as many times as needed for each school they attended.

Are there any add-ons that would do anything like this? I am basically trying to come up with a membership system that allows users to record a list of the children then have, and need something that is more than just one field. It needs to be somewhat configurable and have multiple fields per record. Basically I need a sub-record.

Any ideas?
