I do not need a solution (just sharing information)
I created a spreadsheet that can generating commands to create and modify NetBackup policy configuration.
Now(Mar 24 2013), this sheet is based on NetBackup 7.5, but you can disable each attribute options to fit the commands to your version.
I hope this greatly helps you.
