Hey Georg,                                                                      
You can define a custom resource and use it for limiting.                       
                                                                                
                                                                                
rule a:                                                                         
    input:     ...                                                              
    output:    ...                                                              
    resources:                                                                  
        foo=1                                                                   
    shell:                                                                      
        "..."                                                                   
                                                                                
$ snakemake --resources foo=1                                                   
                                                                                
Now you provide only one "foo" and rule a takes one "foo" on execution.         
                                                                                
Best
