The ability to change the Workflow trigger at the beginning of a workflow

It would be great to be able to change the path from the trigger block at the beginning of a workflow to a different block other than Block A so that if you want to change the actions at the beginning of the workflow, you will not need to manually move them all to block A and instead you can simply change the path from the trigger block to a different block instead that you may have already created. 

For example: If you have branches checking criteria in block A and later make the decision to move the criteria to the trigger instead, you will then have to move whatever was next after block A manually to block A, you currently cannot add the criteria to the trigger audience + delete block A + create a path directly from the trigger to block B
