AoE macro for spells like flamestrike

Hello.

Is there a way to make a macro for spells like flamestrike and blizzard, where you cast flamestrike at your cursor but the spell won’t cast before you release the button you’re pressing? Lets say you have flamestrike minded to “V”. Would like it so when you first press “V” the green marking placement come on screen where your mouse is, but the spell doesn’t cast before you release the button. So its basically like you skip the need to left click, the spell just casts when you release the button.

/cast [@cursor] spell

Or

/cast [@player] spell
