##Yes.

Unopposed grapple, then move the target to standing (which move requires half their move speed). One could argue that it requires the "helper" use half the target's move speed doubled (per moving a grapplee); I've always ruled that the grappler isn't really moving with the grapplee during this maneuver and so the grappler must "spend" half the target's move speed to right them, but not any movement on their own behalf.

In other words, I allow PCs to move to a prone target and right them as long as the helper has half the target's move speed and the grapple-instantiating attack left to spend. But an argument could be made for it requiring a grapple-instantiating attack and the full move speed of the target. This GM finds that too costly for extending down a hand to an ally, but I've heard others argue the other way.
