Pinging Gangplank's Silver Serpents and Ultimate Upgrades

So I have a small gripe with how the ping system works right now. You can't ping Gangplank's Silver Serpents nor how much he needs towards an ult upgrade. This could be really useful if you need a wave that's inbound and want to communicate fast why you need it. Sure you can Alt G to ping the upgrades but It only says "Death's Daughter- Can Purchase" I'd like for it to say "Need X amount of silver serpents" instead of just "unable to purchase" and "can purchase". Is this something that might get implemented in the future?
