Looking for a plugin which update custom field options dynamically

[Anita Y]

Hi , 

I am looking if there is any plugin or solution to below problem 

1)  Create a custom field with expandable text search and drop down .

2) Populate the above custom field with bulk data through API Calls like min 3K records.

3) Refresh the custom field options through a script , here options values has to be updated for every script

4) If the custom field is associated to an issue ,  it should also be updated so the relation won't impact .

Any inputs will be a great help
