QUOTE FORM - How NOT to print bank details on customised Quote form (MYOB AR) (without impacting the customised Sales Invoice form

Hi, client has a customised Item Sales Invoice form - with bank details as text box in the custom form.  Client also has customised Item Quote form - with bank details as text box in the custom form.  They now DO NOT want their bank details to appear on the Quote form (but to stay on the Sales Invoice form).  However, when I removed the text box from the Quote form, it has also taken it off the Invoice form.  Is there a work around for this? How can this be achieved?  Many thanks all!  Donna
