A bindable button combination, Whatever+NUM to toggle to the respective channel (1-Alpha,2-Beta etc..), maybe a small letter could appear next to your map cursor indicating active channel; Now any fly&wait/Dock&wait order you put down, even when having tons of ships selected, should automatically default them to the respective Sync point channel!
I used to make L miners coordinate with S miners on repeat order using sync points, but it just took AGES to set up.. Seeing a horde of S miners take off to go mine, and then return to be transported back to base by the L miner was a thing of beauty, and actually worked flawlessly.. It just took FOREVER to set up the individual orders
