I apologize for not having all the correct terms here, but I don't have a copy of Aurora to reference as I write this. I would like an option that when a divided TF is given the assemble order, that child TF's that are not co-located with the mother TF have an order added to join the mother TF.
What I've been doing is sending a fleet of non-jump grav survey ships along with one jump capable "mothership" in to a system to survey for warp points. The divide option (or whatever it is called, the one that automatically splits a TF in to single ship TF's, one of which becomes the parent TF and all the rest child TF's) is super useful here as it copies the survey orders from the parent TF to the children TF's. And although I've not timed it, it seems that splitting the grav survey ships up results in surveying a system much faster (someone please correct me if I'm wrong about this!). But when done I want to recombine those all back in to the original parent TF. There is an assemble button for that but it only works for child TF's that are co-located with the parent TF. So I have to go to every child TF (single ship TF) and give each of them orders to join the parent TF once they finish their JP surveys. That is a lot of clicking. It is still a heck of a lot better than doing it all manually, but by adding this one additional feature it would be nearly totally automated.
Note that I would like the join order added to the child TF's existing orders, not just replace their existing orders, since they may have a few JP's left to survey at that point.
There are a couple different ways to do this. You can either have the subfleets try to find the parent fleet and merge with them using conditional orders.
Condition: Parent fleet in system
Order: Join Parent Fleet in System
This option has a disadvantage of using valuable fuel if the fleets are 180 degrees apart in a very large system and they chase each other around. Another option is to arrange for a rendezvous point and have the parent fleet absorb the sub fleets. This uses the secondary default order and one set of conditional orders.
Primary Default Order: Survey nearest survey location (or next three)
Secondary Default Order: Move to Entry Jump Point
Conditional Order for Parent Fleet:
Condition: Sub fleets in same location
Order: Incorporate sub-fleets in same location
I've generally used the second option. This seems to work best since the jump ship will usually explore the newly discovered jump points once the survey is complete, and the sub-fleets will concentrate in one, "safe" area.
Hope this helps.
Adam.
