Generate Serial Number Work Order Completion

Hello,

we would like at the moment of the work order completion to generate serial numbers for all the lines (for example if we have qty 10, assign 10 serial numbers at once). Even though in classic it is possible to select multiple rows and then generate s/n for all of them at the same time, it doesn't seem possible in redwood. Does someone know a way to do this without having to click at each line?

Thanks
