Assigning Sequential Numbers to Duplicate Contacts in Clay Tables

Hi Clay team, I have multiple contacts from the same company in a Clay table. If I have 5 contacts from Company ‘X’ is there any way I can use Clay formula to assign numbers 1-5 (1 for first appearance, 2 for the second appearance etc.) as shown in the screenshot below? Many thanks! Link to table: https://app.clay.com/workspaces/226909/tables/t_BC44REwC9Ndw/views/gv_h6ThMEhoMZH3
