Make both the configurable options display and system values be accessible inside $params
Say I have a config. option called Package:
The user sees this as "Package 1"
And $params['configoptions']['Package'] sees this as 1234
Consider making "Package 1" value available here too.
As a workaround in the meantime one could potentially adjust the system value so it passed both values.
Eg: 1234-Package 1|Package 1
Then explode on the - to obtain both.
