How to set default export format in Crystal Reports Viewer

Question

When Viewing Crystal Reports, the top left button can choose export file format, how to set it default to Excel?
If we can only go with hidden the button, and create a new button, any one can kindly provide how to?
The BOE version is XI R2 SP2.
Thanks in advance!
