random encounter site?

[Darth Yoda]

Anyone know of a site that allows a person to type in something like:

7 elves hunting party

and gives
1 5th level leader
1 3rd level tracker
5 1st level hunter

or

6 bugbear raiders
and gives

4th level leader
3rd level bugbear fighter
and four orcs.

Would really be a big help to find a site like this!!!!!!!

There are several sites that offer some randomization or other. I have yet to stumble across one with that level of specificity yet.

The usual site I use for things like that is donjon.
