Hello. We would like to automate the burndown chart for the current sprint. We have a saved query named 'CurrentSprint' and have used the REST API to update this to contain the current sprint. The problem is that we follow 2 week sprints and this is not an option for a burndown chart. To get around this, we use a fixed period. We would like the ability to set this period through the REST API. If this is not possible, being able to set a time frame for the report, such as every X days, would also be acceptable.
