Get Process Schedule and Specific Robots Using API

I download Process Schedule using API - that works fine. I want to also get information regarding ‘Execution Target’ - which robots are selected in particular schedule.

Is it possible to use ‘expand’ for /odata/ProcessSchedules (similar to /odata/Jobs?$expand=Robot,Release for jobs) or is it possible to join data from few different API calls?

Any suggestion is much appreciated.

I found solution - works for Orchestrator 2016.
