Configure working days in JIRA Core

Problem Definition

While it's possible to set up the number of working days within a week, it is not possible to specify which days are workable in JIRA Core.

In JIRA Software is possible to do that by following the steps at Configuring working days, however this is not the case for Core.

Suggested Solution

Add the possibility to select which are the working days in the week (see screenshot).

Workaround

There's no workaround at the moment. The only option possible at the moment is to set up the number of working days as per Configure time tracking.
