I am not mechanically inclined but I did sketch out an idea for a cart mod. It is an "add-on" the would go between an existing 901 atty and the mouthpiece. It is a "T" shaped plastic tube (maybe thin wall PVC??) that would slide into the atty (Like the mouthpiece does now) and that the mouthpiece would slide into. The top part would have threads that a small (1ml ?) plastic squeeze bottle would screw into. the "T" piece would be filled with the poly fill, fluval, etc... you could have the dropper head on the bottle and give a squeeze to keep the cart moist.
Admittedly, it is not the most aesthetically pleasing design, but it would eliminate the need to keep dis-assembling the unit to drip or fill.
Here is a rough (really rough) sketch:
