Other Auto-shrink email message Variables?

Are there any other generic variables available for Auto-shrink email message other than the below?

• %HOSTPOOL%: Returns the name of the affected host pool.
• %HOSTNAME%: Returns the specific host name.
• %HOST_IDLE_DAYS_THRESHOLD%: Returns the configured maximum idle days before auto shrink is started.
• %SHRINK_TIME_UTC%: Returns the exact time in UTC when the auto-shrink task is set to occur.
• %SHRINK_DATE%: Returns the exact date when the auto-shrink task is set to occur.

It would be nice to have username, SKU, Workspace and various others.
