Hide UDF using code

Hello,

We are adding a few UDFs to the Marketing Document Title. These fields are going to be used only on Sales Quotation, so we'd like to make them invisible on all other Marketing Documents (Sales Order, Delivery, ... A/P documents etc.)

Is there a way to do this through code, instead of manually doing it in the UI?

We are on SAP Business One 9.1 PL03.

thanks,

Grace
