Primavera Contract Management 13 - how to hide old/inactive contacts from the general users?

Hi,

We are on CM 13.

There are many old contacts that came over from Primavera Expedition.

For instance some of the contacts are actually deceased.

So to make it easier on the users, we want to hide old/inactive contacts from the contact list without actually deleting the contact entry.

Is this possible?

Thanks.
