QoL change to spellshields

Playing Morg earlier, Thresh hooked me but I spellshielded in time, but my shield broke, he used his Q to jump to me, I flashed just as I THOUGHT he landed on me, and yet he still came with me. Flayed me, and his team killed me.

Could you make it so if he uses his Q on you and you're spellshielded, he STILL gets the ability to jump to you, but only to the point you were standing when he originally hit Q (Meaning if you continue to walk away, he doesn't just simply follow right behind you while you run)
