Ability to "Resend all Fields" for a Roll-up release that sends all fields for all sub-releases to Jira with a single click

I often change the release date of a master release. And I want the release date for each sub-release to be properly updated in Jira. That currently requires that I click each sub-release, and then click "Resend all fields" in order to update Jira. It would be awesome to be able to click once to have the new release date sent to Jira for all the sub-releases. Now that I think about it, it might be a bug, since I already have release date mapped but it does not update unless I "Resend all fields"...
