There are new macro {?EXPRESSION}, new macro function fmtnum(<digits>) and new trigger parameter "Event name" in v 5.2.
That's great, but it's impossible to get a value with a multiplier prefix in the event name this way. That would be good to add the second parameter to a fmtnum() macro function to select a division by 1000, 1024 or return the value as-is if this parameter is absent.
