This is something that has come up for me over and over again. You cannot do anything involving dropdown values in the Add Related Record or Change Field actions.
I would like to the option to:
- Copy a dropdown value to a text field
- Copy a dropdown value to the same dropdown list on another record
The only way to do this right now is to create an exclusive gateway for each dropdown value on the source record and then hard code the value into the field on the target record. This is unnecessarily time consuming and complicated for performing such simple actions.
