Trigger "Filter Assign Scope" retroactively (Possible workaround for JSDSERVER-8461)

[#1]

For Readonly Insight Custom Field, "Filter Assign Scope (IQL)" only takes affect for newly created/updated issues as the filter only gets triggered upon a IssueCreated or IssueUpdated events.

As a result, as a Jira/Insight administrator it's difficult to automatically populate the "Readonly Insight Custom Field" values for existing issues until these issues are manually updated.

As the feature currently doesn't exist, I tried to write a bash script to invoke issue updates.
