Jira portfolio Start and end dates value availability in JQL

Hi,

We are the organization that has strict appointments with our customers. Our PM's do the planning in the Planner and then tasks are being executed by the field personnel who operates with the Kanban board of Jira Agile. When planner optimizes the tasks it works out optimal way of combining the tasks together based upon their priority and desirable start dates and values of start and stop are being generated. I think it will be wise to give these values some availability in JQL so the Kanbn can be generated.

Regards
