Modify nodes in an FSV with underline!!!!!!

Hi SAP Gurus,

In an existing organisation I have created a Balance Sheet through OB58.

The latest requirement is they want to Underline and Bold the Heading Nodes in the Balance sheet and P&L statements.

Can any body suggest me how to do it or there is another process for it.....might be another form needs to be added or something else..

Dont worry....useful answers will be rewarded!!!!!!!

Regards,
