Suggest a better way to receive multiple RMA lines

One of the customers have an RMA with 100 different lines. They are not connected to a CO, but they want to return all of these lines to one inventory location under one Lot/Batch. 

When we select multiple RMA lines from RM lines tab and RMB > Receive Parts… we get the lines like below,

So, users need to select the RMA line by the drop down for 100 times and need to enter the Qty to Return. This is taking a lot of time and inconvenient. 

Is there any easier way which they can return these 100 different RMA lines?

Thank you :)
