Setting up a Tactics Problem Set

On chesstempo, how do you set up a tacits problem set for, say, exclusively mate-in-two? Mate-in-three?

Also, how do you set up a tactics problem set for themes (e.g. Anastasia's Mate, Smothered Mate, etc.)?

You can orginize tactics by number of moves and just go down the line, but I have not figured out how to put them in a problem set either. If it's not possible to do this, it would be a good post in site suggestions. Also you should put "ChessTempo" in the title to get people who use chess tempo to read this. Just a suggestion

Thanks. I believe it is possible. I knew someone who organized a set by mate-in-ones and set it up for me to use. Haven't been able to get ahold of him. I now need something a little more advanced.
