Guild Wars 2

Is it possible to have a shortcut key to toggle Fast-Cast Ground Targeting? If not, is it possible to have it on a per-character basis?
The basis of this suggestion is that:
For an engineer, some kit (grenade kit for example) replaces all the weapon skills with ones that use ground targeting, so it would make playing easier with it.
For other classes, it may be more intuitive to play without Fast-cast ground targeting so you actually places the AoE skill in a better position by previewing the area of effect.

There is an option(I forget where) that where ever your cursor is, thats where “ground-targeting” skills go without having to click twice. Hope this answers your question^^

The whole point is to use that on a shortcut key because even the rifle for my engineer would prefer some aiming (the jump and one more skill is ground-targeted) as oppose to grenade spams

You can fast cast by tapping the skill’s key again too, double tap to place it at your cursor instantly or aim if you need to.
