Is it possible to define important variables used in a ScriptRunner script in Bitbucket somewhere in order to keep the hard-coded values out of the script? This is in case you want to keep things like URLs or other strings out of the script and in a place where an admin can change them in Bitbucket.
I saw a reference that ScriptRunner for Jira Cloud has variables that can be set but I can't find anything for Bitbucket server.
