I would like to implement some automation wherein a custom multi-line text field is preset with particular value(s) when the user selects one or more option from a multi-select custom field.
For example, on the Create Screen for the ticket, there is a multi-select menu with the following options:
The user picks Option A and Option C, then they Create the issue. The resulting ticket then has some additional information in a custom multi-line text field:
Some info pertaining to Option A.
Some other info pertaining to Option C.
Is there some sort of script or plugin I can use to achieve this? I tried using ScriptRunner before but didn't get very far.
