running scripts before task start

I have volumes id like to delete using docker rm volume VOLUME_NAME but dont see a way to do it when the agent receives a new task. Adding the ability to execute a script before a task executes, or specifying the command to run on the instance beforehand would be awesome.

The issue names no files, tests, or entry points. Start by identifying which AWS container service and task lifecycle this request targets, then define the pre-task command behavior and its completion criteria before looking for the relevant service documentation or implementation area.
