Modify 'Friendly name' (label) on custom fields

Issue

• You may be wondering if it is possible to edit or rename your custom fields in Marketo. 

Solution

• Yes, editing or renaming your custom fields in Marketo is possible.
• You can do so by navigating to "Admin" > "Field Management" > Click on the field on the right-hand side field list > click on the name of the field in the centre canvas (UI) then edit.
• Your fields would need to be unused by any asset in order for you to edit/rename them.
