Best practice for capturing key contract contacts

Can anyone offer advice on best practice for storing key contract contacts in Ariba Contract Management.

There seems to be two options, both with more cons than pros:

1. Contact details can be found in the contract; which is saved in documents

2. Contract contacts can be captured by adding them to Team.

We are looking for a more elegant solution so that any user with rights to the contract workspace can open up the project and quickly and easily browse to a list of key contract contacts.

Any help appreciated!
