Can you swap variable values inside a collection through the plugin API

I have a collection of 300+ variables and I need to connect the base values inside to another library, it seems that only the variable Id is exposed and not static, so I’m struggling to find how to do it.

Ideal behaviour

• Loop through all variables in a collection
• Get the id of the value in that variable
• Match to a map with a replacement
• Swap the variable value with the new one
