Actually, you can, but only as a part of the confirm process.

This is harder than it looks because you need code in the onClick to
make the button tag work.

This is something I do on many tags -- I added an extra parameter which
works for text buttons and allows you to attach arbitrary tags to the
<A HREF...>, meaning you can put in an onFocus=something ( [button
extra="onFocus=do_something()" ...] ) or any arbitrary parameter.

But if you want to do what you seem to want you will have to do
it by hand (or come up with a patch to button yourself, for it is
not obvious to me -- you might look at a "pre_onclick=something" and 
post_onclick=something). The good news is you can do it by hand... 8-)

Thanks as always for the suggestion.
