stackable fireworks, pills, etc.

Would like to see the buffy loots from the boxes be stackable so you don't have to sit and wait for so many seconds to do one pill, then a firework, then whatever as you wait for the reload time... Lets see something like where you can combine all your blue fireworks in to one stack, all yellow in another, and they combine the timer on all of them to make it for one lengthy buff, same with the pills, etc. Combine 4 of the 30 minute pills to get one with same pill with 2 hour buff that you won't have to re-eat every 30 minutes... perhaps make use of the refiner to do this in some way.
