Currently triggers can only be set for jobs. Can that functionality be added for tasks as well?

An example:

1)A file trigger sets off a job that sends a file out.
2)A wait task is setup to wait a specific time for a return file
3)**REQUEST** Being able to define a trigger along with the wait task (or any individual task) would start the next task when a file is received or if the wait time is reached.

Right now the only way to perform this is through very cumbersome file checks (or list files) that have retry limits and aren't actively monitoring a location. The other current option is to create a whole new job and have one job trigger the other. Using multiple jobs for this type of scenario causes sprawl in VisualCron and makes administration much more difficult.

I agree that having multiple jobs for something like this causes there to be lots of jobs.
However am not sure about the idea of triggers on tasks, it could make it difficult to read jobs/follow flows
