Hyposprays on emagged medborgs are not emagged

[Roomba]

When custom patches were phased out and replaced with a hypospray, I recall a promised feature was that the hypospray could be emagged and then filled with any substance desired. However, emagging a medborg does not also emag the hypospray, and there appears to be no way to place it on a table for someone else to emag. Unless there's some obtuse method I'm missing (and even then), emagging a medborg should also emag their inbuilt hypospray.
