Optin to default Return Type when doing RMA for multiple lines

Content

We have orders with many lines (100 + lines is a regular scenario). To do an RMA when we select all lines and return all, we have to again select Return Type for each line which is a time consuming process keeping in mind the volume of lines in each order.

Is there a way to default this Return Type to a specific value every time RMA is created?

I havent checked the possiblity of pre-transformation rules yet, will be working on it but any other suggestions are kindly welcome.
