The new

{ITEM.LASTVALUE}

macro is great, but I was wondering if we could get a

{ITEM.UNITS} macro to complete the information ?

I would be able to put in the general email notification:
Last Value: {ITEM.LASTVALUE] {ITEM.UNITS}

At this stage, I'm not expecting any conversion or simplification of the value (eg, displaying free disk space in GB when possible instead of billions of bytes).
