Need code to add multiplyer to result of a query roll: Empowered Cures

So I use    /roll [[?{Which Level|}]]d8 + @{level}    for all Cure spells: "Which Level": 1=Cure light, 2=Cure moderate, 3=Cure severe.  Recently our cleric got Empowered Healing, so all Cure spells get boosted by 50%, but I can't find a way to add the multiplayer to the result and not just get the diminished half-result.   Any suggestions? 

a 50% boost is a 1.5 multiplication, so something like this?: /roll ([[?{Which Level|}]]d8 + @{level})*1.5 EDIT: Not sure if your system only boosts the dice roll or the whole amount, but you can move the multiplication around as needed.

Perfect, thanks for the solution!
