The game currently only asks if I 'would like to remap my controls' but I would like to have the option to duplicate the key's use (this would most likely be followed by a 'are you sure?' warning)

Example - Firing group 1 would have lasers in chain fire mode, then the same lasers would be assigned to Firing group 6 with chain fire. If group 1 & 6 are alt-key mapped to left mouse then 2 lasers would fire together in a chain - This is the desired effect -
Please add this feature.
