User can view progress report "burndown chart" on a sub release timeline instead of the roll-up release date so the team can verify the progress for the month instead of quarter.

Assume each quarter is a roll-up release, for each roll-up there are multiple monthly sub release say month1-month3.

As a user, I want to see the burndown chart for the sprint on a monthly basis so that I can correctly determine any over scoped epics.

Reality, Aha always shows the progress report using the roll-up release date instead of the sub release "date". currently there is no way to define a sub release date leading to an incorrect progress report.

For instance a subrelease Oct (1-30) which is part of rollup with release date of Dec 30

When the user bring up the Oct subrelease burndown report, the end date is Dec30, it should be Oct 30. In effect aha is showing a burndown chart for the release level which is not desirable.
