Add budget hours based on CO items

Currently when create a CO you have to go to Breakdown section to add hour budgets for the CO and we find people are adding the items but forgetting to add the hour budget.

Could an hours column be added to the Manual item add which when save will add to the CO hour budget.

Or a button to calculate hour budget based on CO items.

Lastly the screenshot CO hours Add2 the items have come from Cost DB labout hours so when adding for Cost DB for Labour or equipment the hour budget add as part of adding the cost DB item
