This is much like the request in issue https://bitbucket.org/azhdanov/jiratimesheet/issue/317
Our usage scenario is similar, but more broad. We would like to use the Timesheet gadget as a way to enter time, but what makes it inconvenient is that one has to first log some work during the current period, before that issue shows up in the gadget.
The complicating factor in our case, is that we'd like certain issues to always be in that grid; they are general timecodes. For example, we've made a "General Hours" jira project, and GH-1 is for "Meetings" and GH-2 is for "Vacation", etc. We'd like these issues to always appear on the bottom of the timesheet gadget (or even, a second timesheet gadget that has a project filter).
I really thought I could fake it out, by switching jira.timesheet.plugin.inProgressClause=status = "In Progress" to jira.timesheet.plugin.inProgressClause=project="General Hours"
but then I saw in http://www.jiratimesheet.com/#/wiki/Plugin_Configuration/In_Progress_issues that: "The clause is prepended with assignee = currentUser()"
drat. These general codes will never have an assignee. I guess what I'm looking for is a way to broaden the definition of what issues without a worklog, should appear in the gadget.
