Want to format data entry fields

[Mark]

no one? :(

[Mark]

Would like to pre-format the customer info data fields.
Example, would like to have ( ) and - in the entry field for the phone number.
And have - in the zip code fields and such....
Is this possible?
If not, is it possible to edit the invoice print html file and add these characters in the approaite places?
I would think not since the field is a single data variable.
Any ideas???
We use the phone and zip code formats in our ship label program and need them to be formated that way.
Thanks.
