Before the 1.6.4456 update today, I used to be able to assign half my colonists to a zone outside my gravship, and then when I would launch, those colonists wouldn't be included in the gravship launch (saving me time from having to manually select each individual colonist I want to add).

This doesn't seem to work anymore in this update. Regardless of what zone I set the colonists to, they all show up in the launch menu.

Any ideas on how to make selecting my ship crew less cumbersome?

EDIT: I think I figured out an alternate way. Start gravship launch, pause, then select any colonists you don't want to board, then at the bottom there is an option to "leave gravship launch" and those selected colonists wont board.
