I use all of:
a) IWT them to another target, which can even be a lootable corpse... to bring them closer to the lead toon.
b) Broadcast slave independent movement, which is every toon but the active one... a very brief down arrow press, to end the movement.
c) If they're close to the lead, I press my FTL Follow Me (mapped key) which is hot keyed to a mouse thumb button.

You can play with Strobe too, but I really don't like that.
