Well there's these commands to use:
ce hench_picksquad - select available henchmen where you are standing (in the middle of mission).
ce hench_pickany - select any henchmen from full list where you are standing.
But as pointed out before, you'll get the selection screen if you start the mission from the normandy.
When I open console and enter the code, my Shepard is on the Normandy standing in front of galaxy map (I even tried standing in different places), but the game stil takes me to the cutscene in the kodiak without allowing me to choose my party. I will try using commands that you gave me, thank you!
