I have been trying to research if there's an option in Marketo that would allow creating picklist within the URL builder tool for Lead Source Field. Today the Field Lead Source is manually entered within the URL builder. We have been trying to ask the users to follow the naming convention. But users have a hard time in folllowing the rules and often end up with typographical errors which in turn is affecting analytics. I would like to understand if there is a possibility to design this field to have a picklist, This would avoid bad data.
Appreciate any suggestions.
