Mass Edit Refresh time per tab currently applied per site

Per tab as applicable to all dials on said tab. For example I have a number of sites on various environments. Each envirohnment is on one tab. I want it to only refresh one environment's (tab) sites every 30 mins but the other one every 2 hours. Then when I want to chage the refresh time I can change the rules per tab instead of per dial at present, which saves time.
