How can I schedule jobs / child pipelines under a single pipeline?

Problem to solve

I have a scheduled pipeline which contains Job1, Job2, and Job3. Job2 depends on Job1, and Job3 depends on Job2. When the scheduled pipeline triggers, Job1 immediately triggers. After Job1 completes, Job2 triggers immediately, then Job3.

How can I schedule Job2 to trigger some time after Job1, and Job3 to trigger some time after Job2? e.g. 1 day later and 3 days later

Creating multiple scheduled pipelines (one for each job) does not appear to be a solution, as each job is dependent on its predecessor.

Is it possible for a scheduled parent pipeline to create scheduled child pipelines?
