Looking for macro for cursor position - Earthbind totem

[Lanikai-farstriders]

I’m looking to make a macro that will cast Earthbind totem at my current target, or, barring that, a macro to cast Earthbind totem at the exact center of my screen, or to set my cursor at the exact center of my screen so I can cast Earthbind there.

I have made it as far as:

#showtooltip
/cast [@cursor] Earthbind Totem

I’m trying to do this without installing yet another addon, but I will if I have to.
Thank you in advance for any assistance!!

Not possible. [@player] - your feet, and [@cursor] are the only targeting options for reticle spells.
