Hide Done or rejected Initiatives from drop selector in Feature card Merged

Currently all Initiatives regardless of status appear in the drop down in the feature card when linking through - it would be ideal to not have the done or rejected Initiatives display in the drop down. As a work around we have to rename them and moved them to another workspace. Another suggestion is to say which workspace Initiatives should be displayed in the drop down selector , this means we can just move the epics and not have to rename.
