I personally have a few Keymaps set for Slave Movement.
Four of them actually.

The hotkeys are up arrow, down arrow, left arrow and right arrow.
Each sends to all windows except the current.
And sends a keybind action.
Which is the same as the hotkey.

So on any toon, I can move the others via the arrow keys, without moving the hot toon.

Basically, turn off Follow Strobe.
And press Down Arrow.
