Feature - Custom Fields in Service Contracts (due for r61)

Custom Fields in Service Contracts, need to be able to add custom fields for tagging or grouping. I want to be able to group items like software renewals / or service contracts. very useful if budgeting where you can filter all software contracts and report
Thanks
