If I remember correctly, you could set production priorities in the original WitE. Can you do that in 2.
If you mean with reinforcements (new and shattered/destroyed), then yes I believe you can, but you can only build new units as the Soviet player.
Priority can be set for supply provisions by the player, so you can decide where supplies are going (e.g. you want them to go to a Panzer division before some Luftwaffe field division, etc.).
