Does Dashboard offer a "button clicked" event handler?

Hello everybody,

Is it possible, in a dashboard, to create a callback that will be invoked when a link is clicked?

The link issues an open document request.

I want to modify it by getting a serialised session from CMS and appending it to the URL as the serses parameter.

So I imagine being able to write a an event handler for the button that would call SDK and update the URL.

Is this possible at all?

thanks

Mark
