We have recently moved from Jira Server to Jira Cloud, and one of the add-ons we used was the Role Based Time Tracking. This allowed us to assign individuals to particular roles for an issue, as well as separate estimates for each role (specifically development v testing).
In Jira Server, these were stored as Custom Fields, which I could retrieve in bulk using a filter and `&fields=customfield_1,customfield_2` etc.
With the move to Jira Cloud, these items are now stored as properties, and are available throught the `issue/<key>/properties/assigneeByRoleEntries` and `issue/<key>/properties/timeTrackingByRoleEntries` properties.
My problem is that I can only retrieve these values one-by-one (so 2 calls per issue), and I can't seem to find a way to retrieve all these properties in bulk.
Is this possible at all through the REST API?
