Tracker's Knife

I noticed when jungling you can't let your teammates know how many charges you have left on Tracker's Knife. With items like the sightstones it will say that you have 0-4 charges left. It would be awesome if the Tracker's knife could get the same treatment. I don't know if this is a bug or intended so I thought I would post here just in case.

1. Bring smite as a summoner spell so you can get the jungle items (Doesn't matter on the champion)
2. Get enough gold to get Tracker's Knife
3. Hold the left control (or whatever you bind that key to) and click on tracker's knife
