Direct print 2 copy sales invoice

Any one please help me how to add button for printing 2 copies of sales invoice while saving the invoice

 

Its available by default.

 

need additional button that can set "number of copies" to 2 and "type of copies" to All without pressing the "Alt + C " in printing page
So far i've made this


[Button: GetDoubleCopy]

Key : Alt+2
Title : $$LocaleString:"2 Copies"
Action : Set: SVPrintCopies : 2
;; Action : Set: SVPrintCopy : $$LocaleString:"All" ((((This action also need perform with this key but not working))))

[#Form: SV Print Config]
Add: Button: GetDoubleCopy
