Can I add a possible setting index in GUID?

I am trying to convince my tablet to turn off the display when the lid is closed. I get this:

Subgroup GUID: 2e601130-5351-4d9d-8e04-252966bad054 (Idle Resiliency) GUID Alias: SUB_IR Subgroup GUID: 48672f38-7a9a-4bb2-8bf8-3d85be19de4e (Interrupt Steering Settings) GUID Alias: SUB_INTSTEER Subgroup GUID: 4f971e89-eebd-4455-a8de-9e59040e7347 (Power buttons and lid) GUID Alias: SUB_BUTTONS Power Setting GUID: 5ca83367-6e45-459f-a27b-476b1d01c936 (Lid close action) GUID Alias: LIDACTION Possible Setting Index: 000 Possible Setting Friendly Name: Do nothing Possible Setting Index: 001 Possible Setting Friendly Name: Sleep Possible Setting Index: 002 Possible Setting Friendly Name: Hibernate Possible Setting Index: 003 Possible Setting Friendly Name: Shut down Current AC Power Setting Index: 0x00000001 Current DC Power Setting Index: 0x00000001

I want to add this:

Possible Setting Index: 004 Possible Setting Friendly Name: Turn off the display

This is the Registry

\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\4f971e89-eebd-4455-a8de-9e59040e7347\5ca83367-6e45-459f-a27b-476b1d01c936

Suggestions? Thanks!
