Capitalization of Names from Form Submissions

Hi All,

When users are submitting forms on our web pages they are sometimes inputting their names as all lower case or all upper case. This is obviously an issue when we send out email communications using tokens for first/last name and the names are in improper format.

Is there a way to add validations to control form field submissions on Marketo forms? Ex: if a name is entered as "joseph" --- update the name to read "Joseph"

Thanks!
