Lock the car by radio when the door is open

Hello all, I have a question about locking the RAV (BJ2013, no keyless) by radio remote control: is this possible if the rear door is still open? I have the following problem: I get my little girl out of the child seat, maybe still have the baby bag in my fingers, close the door with the elbow and then have to reach for the key and lock it by radio. There are also cars that do this differently: you press the button first, you are already locked (without jedoc h first to blink) and then when you close the door, it flashes for confirmation. Can you manage that somehow also on the RAV? Thanks and greetings, Mark
