Autocar is a “complete and await response” plug-in that supports automatic naming and tagging. It completes one or more actions and creates follow-up waiting actions to remind you that you’re waiting for a response.
For example, if you just called John about going hiking on Saturday, you could use Autocar to mark the action complete and create a follow-up Waiting action in one fell swoop. The new action’s note includes the date and time you completed “Call John,” plus a link to the original action.

This plug-in is highly customizable. Hold down the ⌥ Option key when choosing “Complete and Await Response” from the Automation menu, and you’ll see some options, including a few choices for the name of the new action. You can also edit the “Autocar settings.txt” file included in the plug-in to fine-tune many aspects of its operation. See the documentation for more information.
