Personalize a Program-Defined Field

AR Customer Maintenance has this great field on the Main Tab:  ML_Warning that displays info about a customer's credit status.  Our client wants to change the appearance of the field to make it stand out:  increase the font size, change color of the text.  Is there any way to do that?  Or is ML_Warning available to insert into a script to place elsewhere on the form?

Any help would be appreciated.
