autoprogramarse

Used both for people organizing their own schedule (autoprogramarse las tareas de la semana) and, more technically, for systems or software capable of modifying their own code or behavior.

• Prefiero autoprogramarme el horario según mi energía del día. — I prefer to schedule my own day according to my energy levels.
• Los investigadores diseñan sistemas capaces de autoprogramarse. — Researchers are designing systems capable of self-programming.
• Autoprogramarse las vacaciones evita depender del jefe. — Scheduling your own vacation avoids depending on your boss.

Context decides the meaning — with a person as subject it's about scheduling one's own time; with a machine or software as subject it's the more technical self-modifying-code sense. Don't assume one meaning without checking the subject.
