[Mauiusers] Restricting allocation of certain node types

Dear all,

Is there a way to tell maui not to allocate certain "type" of nodes unless and until it has been asked for?

For example, I have four nodes

node1 np=4 slow
node2 np=4 slow
node3 np=4 fast
node4 np=4 fast

Here, I would like to have maui allocate only the "slow" nodes by default. If the slow nodes are not available and a new job with a simple request "-l nodes=1" comes up, it should be queued rather than having a fast node allocated for it. However, of course if the "fast" job is explicitly asked for, then it can be scheduled. That is "-l nodes=1:fast"  should be accepted and allocated one of the free fast nodes. 

Is there a way to do this?
