Need to apply an interface template only to gigabit interfaces

Need to apply an interface template only to gigabit interfaces

I need to change all my existing gigabit interface thresholds from 30% utilization to 3%. I used the "Interface Templates" to create a new Ethernet template, but when I click "Select Interfaces to apply", it requires me to manually select each interface. The list does not show the interface speed, but I need to leave any 10/100 interfaces at 30%.

Basically, how can I apply my interface template to only gigabit interfaces on a device that has a mix of 10/100/1000?
