We're setting the summary of an issue based on what is in a few fields, and one of which is a multi-select field. To make sure we aren't modifying the options that were selected, we're copying the values of the multi-select into another multi-select field for temporary storage in order to remove some of what is selected, and then use the remaining value as what's included in the summary. The problem is, I haven't found a way to do this yet. Is this possible with Automation, or will I need something like ScriptRunner?
e.g.
Summary: {{Field1}] {[Field2}} {{Option from field 3}}
field 3:
value: 1,
value: 2, (Desired value)
value: 3
