In Micro-pose's X-COM you could do these;
Prime any device for 0 seconds and place it on the ground in your Inventory Screen? Not the possible here? If so, how? Will it be added?
On the battle-scape I cannot swap different ammunition in and out for the Rocket-launcher? If so, please tell me how?
The C-4 charge cannot be primed for 0 seconds then thrown in the same turn? Please tell if it can be done or will be allowed?
