Alternative property editor to checkbox list

Hi,

We are using a checkbox list property for selection multiple items from a list of items. The problem is that it contains over 100 items and becomes extremely long in the UI. We want to replace this with an editor which uses two select lists. All items are available on the left side then you can pick the ones you need and move them to the select list on the right side. Does this exist in episerver or has anyone done anything like that before? Otherwise could someone point to some tutorial or documentation for building it ourselves?

Thanks.
