[General] How to make Kaboom! to be single target spell?

[AtivEnergy]

Greetings!
As title say, how can I made Kaboom! to be single target spell (building/unit/trees and ground? (Just like in dota 1)
I don't want to see that Aoe circle when I select the spell.
My Goblin Sapper has to die when he destroy/explode just like the normal spell.
Also, I wish that this spell can damage trees.(optional)
The spell will be just level 1, but I need to be able to set the AOE and the damage.

The help will be appreciated!

Maybe you can use Unstable Concoction instead and change the allowed targets

Unstable concoction is ugly and have other problems.. thank you anyway!
I prefer something like this.. but I have no idea how to do it.. this is dota 1 map..

Bump
I just need the Kaboom! ability to be used at least on building/unit and ground but with single selection target, not with aoe circle.

I want to be like this:

It is possible on latest patch? @Uncle

Edit Important: I noticed that in patch 1.26, this Kaboom! (Goblin Sapper), works exacly as I wanted, but this spell is changed by default in Reforged.
How can I obtain the old spell from 1.26 on 1.36?
