Allow players to queue for multiple duties at the same time

[Avatre]

I think the problem OP is stating is that they want to be able to pop the queue serially. As in while doing the first they want to keep position in the 2nd and 3rd and be able to pop straight into those after the first is done.

Right now you can queue for 5, but as soon as you get one you drop out of the other 4.

And that in itself would cause problems quite likely with reserving a spot while they are already bound by a duty. Most likely doing something like that would hinder other people from getting into a duty in a timely manner, and essentially cause the person queueing like that to end up jumping the line of people who have been waiting for a duty to pop
