instant creation of task in request fulfillment module

Hi,

I do like to have the same task creation function for request fulfillment as in incident module, can pls share some knowledge and guidance on how can i achieve it. (click on a button, a form will pop up allow user to fill in required field click save to open or click cancel to stop the action)

I had check in incident there is a rad process (im.task.open) which will create the task, but it seem there isn't such process for request fulfillment.

Thanks in advance.

Regards
Soong
