Yes, that is possible.
Let's say your table is called Clients and you have a field ClientID that uniquely identifies each record in that table.
In Manage | Database | Relationships, select Clients and use the button with two green plus signs to make a second table occurrence "box" that refers to clients. You can rename this new occurrence, AllClients.
Drag from any field in Clients to any field in AllClients to create a relationship.
Double click the relationship line and change the relationship operator from = to x.
Place a portal to AllClients on your Clients layout.
Put the fields you need from AllClients in the row of this portal to properly list all your clients.
You can either select these fields and use Button setup... to peform the following script, or you can add a button to the portal row for this purpose:
Set Variable [$ClientID ; AllClients::ClientID ]
Enter Find Mode 
Set Field [Clients::ClientID ; $ClientID ]
You can even use conditional formatting with this expression: Clients::ClientID = AllClients::ClientID to specify a Fill color for the portal fields to "highlight" the row in the portal that corresponds with the current record visible in the Clients layout.
Thank you for your answer. The steps you gave me worked perfectly. Ye!
A follow-up: when I show the layout, it shows me some record already in the fields. Is there a way to have an empty layout?
I think this should work. Use a a script to set up a found set of zero records. Run this script when you first select this layout:
Show All Records
Show Omitted Only
