Save and Custom button as 1 Button?

HI
Is it possible to make from a Custom Button also the Save button?
{BEGIN save_button}

<A class="rnr-button main" href="#" {$savebutton_attrs}>

{mlang_message SAVE}

</A>

{END save_button}

<A class="rnr-button" id="New_Button1" href="#" typeid="ib">

CONFIRMATION

</A>
Kind regards,
Ivan
