Persistent Context Set Previous Value

General

Hi All,
Question: Is it possible to set previous value for a global value, or should I just send two values pushing the first one to the previous value state
Thx

Sorry, I'm trying to work that out.
You want to restore a value that was previously changed?

if so, yes - you need to store it somewhere, so you can re-call the value, to restore it.

Maybe store as an array of two entries. Current and previous. Or as an object with myvar.current and myvar.previous.
