In Field Service Mobile when a User does a long press at the Work Order Service Task subgrid on the Work Order form or the Work Order Incident form, a new Button on top of the subgrid "Mark Complete" appears.
We want to configure that button so that after the User has marked records and pressed this button, not only the Percentage Completed gets updated but also a new field gets filled.
But how can we configure the additional step to be executed by the button?
It seems like the command behind the button is called "custom_MarkComplete". But how can we customize it?
