Capture Signature without intermediate screen

Hi

i am working with SMP3.0 SP8 + IOS9+ Ipad.

I have one screen where i have to capture the signature of the user. I have written the transaction and also the screen for transaction. It allow user to navigate to the screen then he click on sign button and new screen will open and he will able to make the signature and click on and it will redirect to original transaction screen and he click finish and the data is saved. All are working good. But now my requirement is i don't want the intermediate screen where user have to click sign button and then the capture signature screen open in full screen. Is there any way it can be done.
