Prevent Invoice export in some formats

Hi

In AX 2012 , I have a requirement to prevent users from exporting Invoice to Excel , word , XML ...  and allow user to Print and export to PDF only .

There is a fear that user could get invoice on word document , and then change the Bank account number for example ...

Is there a possibility to prevent some "reports" like Invoice for example to be saved/exported into some formats.

These excluded format should be still available for all the others reports .

Thank you

best regards

Edouard
