[slurm-users] Is it possible to select the BatchHost for a job through some sort of prolog script?

As the title suggests, I’m searching for a way to have tighter control of which 
node the batch script gets executed on. In my case it’s very hard to know which 
node is best for this until after all the nodes are allocate, right before the 
batch job starts . I’ve looked through all the documentation I can get my hands 
on but I haven’t found any mention of any control over the batch host for 
admins. Am I missing something?
