Make Syringes Auto Switch To Inject When Filled?

[Roomba]

Eh. I wouldn't want to be rapid clicking drawing my blood and have it just inject it back into me.

You should be able to hit C if you are in WASD mode or page down to switch it.

Necromancing this thread because this was implemented, and this problem has indeed come up quite a bit. Maybe I'm just ham-fisted and set in my ways, but I'd rather spend the extra button click to switch modes than spend a minute drawing and injecting from the same container because a lag wave hit and I clicked too many times.
