We do not have an option to select all instances of issues, checklists, tasks and equipment’s. This is a big issue because the CCDI volume of data it is really, really big (more than 40.000 tasks). If we want to delete these tasks we will need to go for a workaround selecting one item, hold shift and then click in the list to make a mass delete of items. We know that there is a button for “edit all” so I think it is an easy thing to do a “select all” button.
