It depends on how you intend to select actor 2,4. I think there are plugins that will let you specify a certain frame (Galv had a Move Route Extras script for Ace that did that - I'm not sure whether he converted it for MV). I don't know whether they'd be compatible with this plugin, but you could give it a go.
Archeia also wrote a plugin that let you choose a specific frame. You might try setting the direction, doing a script call to select the index, followed by another script call to set the pattern and originalPattern to the correct column (in your example, the direction would be 4, the index would be 1, and the pattern & original pattern would be 0).
