custom action to change a sort order

custom action to change a sort order

so i have made my zoho creator app to manage my service calls and i have a view to see jobs scheduled on the present day. Each job has a field called routing priority which is populated by a pull down menu that has a choice of one to ten and the view sorts them accordingly. So im looking to make custom action buttons to move the priority up and down. Has anyone ever dones something like this? Basiclly the up button would move that job from 5 to 4 and job 4 would become 5.
