It is possible to have a control node that makes engineers prefer to repair non-military ships? I generally like to automate my empire wherever possible, and this generally means leaving my engies on FRD. However, their tendency to get bogged down repairing any fleet I have stationed in a system is annoying - I would much rather they spend their time repairing my turrets, resource harvesters, force fields, etc, especially when I already have an MRS in the system.
