Allowing appending to existing files
Created by: iamcalvinlau
Currently, it seems like writing out data can only create/replace a file/directory of files. I would like to be able to append to an existing set of files.
For example, currently, if I run a job with 10 steps, then re-run the job with another 10 steps; currently, I will see just 10 steps in my bp files instead of 20 steps. I would like to be able to aggregate the 20 steps into the same set of bp files instead.
