Hello there,
I am trying to get Butler to assign a new value to a Dropdown Custom Field. This isn't working if the dropdown doesn't already contain the input value as an option for the field.
eg: When "Buyer -> Owner" button is pressed, set custom field "Owner" to "{{%Buyer}}" (Owner is a dropdown custom field)
How can I add a new option to a Dropdown Custom Field through Butler if this functionality doesn't work (from another variable if this is possible)?

I am not wanting duplicate option values inside a dropdown, I just need to add the option if it does not exist already, then set the value (regardless if it previously existed or not).
Thank you so much!
