Tristana QOL tooltip for E

Can you please make Tristana E have a max damage tooltip. This is done for Twitch E max stack it says it in red when you hover over it. It is a complex complication to calculate since it is as follows.

MINIMUM PHYSICAL DAMAGE: 60 / 70 / 80 / 90 / 100 (+ 50 / 65 / 80 / 95 / 110% bonus AD) (+ 50% AP) Tristana's basic attacks and abilities against the target increase Explosive Charge's damage by 30%, stacking up to 4 times for a maximum 120% increase, upon which the charge also detonates instantly.

BONUS DAMAGE PER STACK:» 18 / 21 / 24 / 27 / 30 (+ 15 / 19.5 / 24 / 28.5 / 33% bonus AD) (+ 15% AP)

does it work like this? lvl 1 tristana with dorans blade and a max bomb does (60+((18x4)+(.15x8))+(8x.5)=137.2 how I calculate it is roughly quickly its 2.5x whatever the base bomb damage is so if its 60x2.5=150
