I think this is what you are looking for?

Hi Erwin,

Thank you for your reply, but what im looking for is if possible to add button or icon on the fields in the form not on the grid cell (not the double click -  because this is not really obvious from the user).

like the arrow I point on the image above.

Thank you

​@Jheng There is no standard functionality that allows to position a Task in a Form. You could however get such a scenario working by using an HTML field where you (for instance) display an Icon that upon click triggers a deeplink to a Task. See below topic and Release notes for reference:
