Setting up recurring tasks

We are using as a compliance workflow tool. As a result we need to set up recurring tasks, though we also want to store completed tasks in their own board once they are complete. The logical workflow / automation needs to be something along the lines of:

  • If status is changed to done
  • Duplicate item
  • Move item to Completed Board
  • Push out Due date by 3 months
  • Reset status to not started
  • Delete contents in evidence column

The problems I have with this are:

  • All changes are made to the task that has been moved to the completed board rather than tasks that are still outstanding in the new board
  • I can’t find an automation to delete items

Any help here would be very much appreciated thank you.
