Button in summary view


it is possible to define a button in the summary toolbar or maybe in the Total line ?
Currently If I define a button they will be shown only in the detail view.
what I wil do is, to store the values from the total line in an databse table and so I can use them in another application

Thanks in advance

Has somebody a solution or a hint for this topic?
It would be very helpful for me.

Well, since on summary the OnScriptinit is executed, you can put there js code that add a button in the toolbar (using jquery), but the button will execute js code, so to store somenthing I guess you have to call in js an ajax call to a blank app that will sotre in the DB what you pass as parameter.
Tricky but possible.
