Often processes will need to go through a Dev/Test/Prod workflow where referenced resources/data/urls change depending on the environment.
When only one reference needs to be changed, it is straight forward to setup a Choice Parameter that allows the environment to be changed
What would be great is if there could be multiple values stored against each choice.
these can be referenced in a similar way to either lists or JSON objects
If Test is selected, then
$(PARAMETER[0]) = testapi.com
$(PARAMETER[1]) = test.sde
or
$(PARAMETER["api"]) = testapi.com
$(PARAMETER["sde"]) = test.sde
