Saving pipeline step information

I have drone running Terraform. I’m working on parallelizing the terraform plan steps across aws account boundaries.

However, that means I need to aggregate that terraform plan information from multiple pipelines.

Is there a straight-forward way in drone to say “Hey drone, keep this text based information for the life of the build number. Something later in the build process will come and grab it?” (note: i’m assuming that multiple pipelines share a build number)

As I describe this, I’m guessing the answer is “use some other data store to cache this information”.
