Exporting Report of All Tickets with Comments as CSV - Can Internal Comments be filtered out?

[Sean Poole]

Hi, 

A Customer has requested a report of all our tickets with them, but they also want us to include all the comments leading up to a resolution - so that they aren't exposed to internal discussions between support team and our own development team, is there a way to export this without internal comments showing up?

Thanks and regards,

Sean from accessplanit
