The problem I have is, that my tasks fail because of UnmetDependency. The dependency can only be met after I ran some code on the engines, which obviously needs to run before a task is given an engine. If a task is given before my code was run, the task will always fail.
A workaround could be to have a 'disabled' mode (for parallel tasks) for an engine at startup. Then it would be possible to run special code on an engine via direct view, 'enable' the engine and finally receive parallel tasks.
