Not sure I understand. Do you mean to add "H:C:T:L" to "drivetemp" ?
That would make it something like "drivetemp:H:C:T:L-scsi-8-140".
Not sure if that is really useful, and it would at least be partially
redundant.

"scsi-8-140" is created by libsensors, so any change in that would
have to be made there, not in the kernel driver.
