Retrieve existing item configuration

HI All ,

Wanted to know if is there anyway to get product configuration data for existing item present in Quote .

Scenario : user configured one item and closed the Quote , now he wants same configurations data and attributes for same item in new Quotes

How can we get it using system id or partNumber or any different approach .we don't want to reconfigured using scripts which will lead to performance degradation. When I checked every main item is having Configuration Id, is there anyway to achieve similar behaviour ?

Thanks
