button action

Save widget value without submit

Hello,

Im using Bonita 7.3.1. In a form, I have a areatext widget and a button. The input save the areatext value in a bdm value when I submit the form, but if a user write some text in the widget and close the form without submit, the value is lost. For this reason, I want agree a "save" button, which save the value if the user want close the form and continue later.

I can do it, with a submit button and a cycle flow in the same task, but ¿Some way to do it without submit?

Thanks
