Set reporting day - Time Reports and Gadgets for JIRA Cloud

The old JIRA Timesheet Reports and Gadgets plugin allowed users to set a reporting day (see image 1). The new plugin "Time Reports and Gadgets for JIRA Cloud" doesn't have this feature. This feature is needed by our company. We would like to set the reporting date to a Saturday.

Under Language & text (Mac computer) the start of the week is set to Saturday.
