Can I reduce the number of jobs zppy launches?

Yes, the job bundling option introduced in #243 can be used. For an example configuration file, see https://github.com/E3SM-Project/zppy/blob/main/tests/integration/template_bundles.cfg.

Notable:

You can use [bundle] to specify bundle-specific option.
You can add a task to a bundle with bundle = "<bundle-name>".
Subtasks can be placed in bundles other than the default from their parent task. (e.g., bundle = "bundle2" # Override bundle1)

Can I use bundle at the top of the configuration file so everything will be in a single script?

It's not specifically tested in our test (https://github.com/E3SM-Project/zppy/blob/main/tests/integration/template_bundles.cfg), but I'm almost certain that it works. E.g., set bundle = "one_bundle" in the [default] section.
