Missing SAVE button after modifying payment option

Hi there,

just wondering would it be possible to place a SAVE button to on the page, where payment options are entered / modified? If so, wouldn't it be nice to switch then - after saving is done - back to the main level?

It's an irritation after entering the selection... if the option is saved or not. Especially after modifying a selection it takes quite a while until the changes are made. Meanwhile all what's visible at that stage is...

nothing....

Am looking forward hearing from you guys.
Thank you
