Exporting with many2one or many2many fields has an undesired effect for us. Namely gaps in the generated table:

current_object_field_A        many2one_field_A1
                              many2one_field_A2
                              many2one_field_A3
current_object_field_B        many2one_field_B1

What I'd like to get instead is this:

current_object_field_A        many2one_field_A1
current_object_field_A        many2one_field_A2
current_object_field_A        many2one_field_A3
current_object_field_B        many2one_field_B1

Before attempting any module development I'd like to see if anyone has a quick fix for this. Ideally I'd like to have both options rather than completely replacing the original as I know it's important for data imports.
