In effect, these profiles can be used to simulate custom field functionality by utilizing the fields on a case-by-case basis. For example, as the fields in Collaborati cannot be changed, a client might need the "Clerkships" field to house a unique alphabetic timekeeper ID. With client-specific timekeeper profiles, a Firm Administrator can link a profile to that client and fill in the Clerkships field accordingly without needing to create duplicate records or interfering with other clients who do not need to change Clerkships to function as alphabetic timekeeper ID.
Client-specific timekeepers were added to Collaborati as of Collaborati 3.3. These client-specific timekeeper records exist on the main timekeeper record, and provide a mechanism to show different content per field depending on the client viewing the timekeeper.
