By default, the Client list is set up to just display information about the primary contact for each of your clients. But what if you want to see information for all contacts for that client here in the client list? 

Open the Client list via Clients > Client list:

Click Custom view > Edit columns.

Click Add new column, then add any contact fields as columns. In this example, we will add First name and Last name, however you can add any other fields within the Edit contact/Contact details section:

Click on the cog icon at the top of the First name column.

In the Column options box, under Show Contacts, select All and click OK:

You'll now see any clients who have multiple contacts will be showing rows for each of those contacts:

Select Done when finished.
