HCI Global Variable by Groovy script

Hello friends,

Is is possible to access the Global Variables by groovy script in HCI? I need to access and modify.

I want to use the groovy because it is not possible to use the Write Variable passing in the name of variable a dynamic parameter. like ${property.DynVariable}, HCI will create a variable with name ${property.DynVariable}, not with the value of this property.

Thank you
