Should there be a toggle allowing the cast of Rescue on someone?

When she spreads her wings, you move out, when she tucks them in, you move in. It's a tight timer ya, but simply looking tells you more then the AoE marker tells and before it shows.

And yet, people still screw it up, which is a valid place for Rescue to be used that can't be covered with more healing.
