Add-on for JIRA: Is it possible to avoid storing password information in clear text in config.ini?

We got the Add-on for JIRA for Splunk Enterprise working ( https://splunkbase.splunk.com/app/1438/ ) however it requires us to authenticate using credentials that are stored in clear text in C:\Program Files\Splunk\etc\apps\jira\local\config.ini, according to the instructions. Is there some way to avoid that, and have the Splunk end user SSO against it instead? We require this for 2 reasons: 1. For obvious security reasons, we don't want to store the password in plain text on the file system. 2. The account used in config.ini will not necessarily have access to all the JIRA projects anyway, and as a result not return all stories/issues that we're querying for. Each user will be querying for issues in JIRA projects that other users may not have access to. We could use a JIRA admin account, but then refer to point #1 above. Bonus question: Is there a way to query multiple JIRA instances? We have a few instances that we'd like to reach into at the same time.
