Add a label using Automation, without changing/removing existing labels

[Alex Bernardin]

Using the Automation add-on, I want to have a rule/action such that on a specific transition, a label gets added to the labels field.

When I set this up using the 'Edit field' action, I found that the new label would be applied, and existing labels would be removed. 

Wondering if there is a different action I can use to add a value to a field without replacing the existing field value?

aaaaaand, as so often happens, I've answered my own question.

When you use the Edit Field action, there's a text field for entering the new value.  To the right of that field there's an elipsis overflow menu icon.  Clicking that icon gives you options for adding or removing explicit values from the field, instead of just replacing the field.

Thanks for this post. I got caught in this and didn't see the hidden menu.

For the sake of clarity, the top field is for values you want to add to the issue.  If you want to keep the other values intact, you leave the bottom field blank.
