How to have a Jira Service Desk automation rule, not to overwrite a value on a field?

[Sebastian Pedraza]

To clarify, we have JSD configured with automations, and one Custom Field has multiple options (we can select more than one). The issue is that when the automation quicks in, it "edits" the Custom Field with a value but in the process removes what we selected manually. 

Why do we have the automation do that? Because the field is mandatory so if we don't select it, the automation can not run.

What we would like is for the automation to "add" a value,I would imagine this is similar to adding a label instead of removing the existing ones and creating another one.

Any ideas on how can I work around this?

Thanks!

If the automation is triggering on a post-creation scenario then make the field required for Create only. This will allow the automation to skip touching the field.

Excellent, we will try with that. Thanks!
