Populate picklist with external data

Populate picklist with external data

Hi, I am currently working on building a request workflow that needs some drop-down fields that are going to be populated with data accessed via REST API, I am aware that custom schedules can send API Requests to external services via python or deluge, but I am not sure whether there is a way to control what options are available in a request custom pick list field. If this functionality does not exist I have a few other things to try, I just wanted to make sure this isn't currently possible before moving onto other paths
Oh and I am currently working on a server running On-Prem version 15250
Thanks!
