How to add new values to select list field in jira dynamically or using plug-in

Question

Here is the my use case.
1. I have a "Customer Name" text field and "All Customers" single select list.
2. When issue is resolved I want to pick value present in "Customer Name" and want to add in "All Customers".

I am able to achieve this If a value to be added is already present in "All Customers". But I want to populate "All Customers" field with new value if it is not present already so that in future it is available for selection. How to do this? is it possible to do so?

and I found my answer. Here is the complete code. its jira plugin that raises on resolved event and takes value from one custom field and populate another one. Hope that helps other people.
