Each line request date is required when booking return order for ATO item

When create return order for ATO item, after I entry Return Reference as sales order and selected the details order number and line number, system will display the ATO model item as first line.

Then I entry the Request Date for ATO Model line and save.System will create Configured Item line and option lines automatically below the Model line, which Request Date has no value.

When I book order, system will give error msg: Request Date is required on a booked return line , because the lines created automatically has no Request Date

Is there any way to avoid this question? It will be a hard work if User must entry Request Date for each line one by one
