Custom UI Ribbon Editor - If Then Else - Is it possible?

[lnagel]

I would like to show one set of Excel Ribbon Menus for the condition of :

Filename = Ribedit Condition1.xls

and a different set of Excel Menus for the condition of :

Filename = Ribedit Condition2.xls

Is it possible to accomplish this in the XML code?

If not - any other thoughts would be appreciated

Thanks in advance
