Doesn’t look like that’s possible 
the coding relies on using if, else and the points system and unfortunately I’d need 2 conditions to make the same move but unfortunately don’t think we can do that for example lets say the dark blue block was at the too of the screen. In order for it to go to the bottom it would need the following,
If (column4-6 =0) {
Blueblock shifts to (shift number)
}
But this also depends on where the blue block is and weather I need it to travel up or down so I would also need to add points to the blue block to give it instructions in which way to travel. So example
if (Blueblock =0) {
@overlay blueblock shifts to (shift number up)
}
Else {
Blueblock (shift number down)
}
But the conditions for the travel direction and the column conditions (if anything is blocking it) would need to go together.
I don’t even know if this would work using the other methods either 
But a massive thank you 
it’s always nice to have suggestions xx
