Yes. altq is what you are looking for.

If all you want to do is limit the bandwidth for a simgle machine, you
can set up a default queue with total bandwidth equal to total outgoing
capacity, then set up a subqueue with the max bandwidth you want that
machine to use, then write one or more rules which pass the traffic from
that machine on the smaller queue. Let the rest of the traffic you pass
use the default queue.
