No there is no way because PBS works primarily by FIFO. What I do is: first I search Boxer shelves. You do not have to be a Boxer to search their shelves. You just can't make a Box deal with them. It's just a possible way to lead you to someone's shelf who may have more than 1 of what you are looking for. If that doesn't work, then I open 2 PBS windows. I order a different book on each window and then check their shelves using the Order More From Member button. Again not fullproof but frequently I find that 1 of them will have more than 1 of what I'm looking for and that's the order I complete. I would say since each book has so few copies posted, it's probably slim that anyone has all 3. But you could open 3 PBS windows and start an order for each book and see.
Another thing to try is to post in teh book bazaar for what you are looking for and see if anyone has all 3. I would suggest that you could put it in your signature but you don't appear to be an active forum user so it's unlikely many people would see.
