Help on multi reference footnote

[Flink Del Dinky]

Is it possible to refrence an existing footnote instead of creating a 
new footnote?

I tried labeling the foot note then cross-refrencing to it.  That 
actually worked except the cross-refrence was regular size text and not 
superscripted like a regular footnote.

I've looked for a superscript menu option but couldn't find one.  I 
aknow in math mode you can get superscripting by pressing the '^' key. 
But you can't do cross-refrencing in math mode.

Any ideas?
