How to set specific trigger depends on disk name (windows)

Hi,

i have a windows server 2016 with 2 disks C: and D:

Currently i have my alerts based on this configuration : 

But my problem is that D drive is almost 800Go and thus i don’t need to get the same values about when the disk space is at warning or critical.

How can i have this configuration for my C: drive and a specific one for my D Drive ?

Thank you
