Default attributes for clusters

Help
1

I have a series of clusters that look like this:

subgraph cluster_theory {
    label = "Computer Science Theory"
    bgcolor="#F5FFFF"
    fontsize=30
    penwidth=0
    margin=20;
    COSI121B;
    COSI130A;
    COSI133A;
    COSI180A;
    COSI29A;
}

Is it possible to set those attributes once in one place, instead of repeating them with each cluster?

I’ve scoured the doc, and I can’t find it. I did see how to set default attributes for a node, but not for a cluster or subgraph,

Thanks

Sure, just use graph [ ] to set subgraph attributes.

graph G {
   graph [
      bgcolor="#F5FFFF"
      fontsize=30
      penwidth=0
      margin=20
   ]
