You can't reload a single context, maybe they will change this with a next major. Copying a checkpoint is also not possible imho. So if you delete a context the whole checkpoints are gone.
If you want to do a write erase and reload for a fresh start you have to create an initial "empty" checkpoint and roll back.
Easiest way to create a fresh context and make sure it has the same configuration is copy and paste from a config file but you have to be careful in which order. If you e.g. reference a cert which is not in the store or paste an ssl-proxy into a service policy without the ssl-proxy part configured etc.
But as always maybe someone has even better advice.
