OK, I now made it such that dau and cau are treated as hop onto friend/foe-only, and are treated just as pa. That means you can still have another locust capture or unload square on the same move, and the unload would then refer to the piece captured in the destination.
I am afraid that what you want still would not work, because the slider could also hit the board edge, and there doesn't exist any method yet to 'sense' that. I once considered to allow o in non-final legs to allow the leg to go off board (or onto a 'hole'), but it conflicts with the use it has now for indicating cylindrical pieces. Of course a new modifier could be introduced for this.
Problem is that at best its use would lead to contrived solutions. If new symbols have to be introduced, it might be better to introduce something that directly does what you want: force a slider to its maximum range. Like we already have W* for moving up to half the board. E.g. R$ (or perhaps W$ ?) could mean 'only the farthest accessible empty square. You could then write Q$cQ.
