Is there any way to get the list of sub-contacts for the current contact in tasks, contact summary, and targets?
For example, can we retrieve the list of CHW areas under a supervisor’s area or the list of patients within a family?
Thank you!
Currently no.
However, we are close! 
I think the hard part is actually already done, in that the cht-datasource API is technically already accessible from tasks/targets/contact-summary. Unfortunately, it is currently impossible to use most of the features since the tasks/targets/contact-summary code cannot make async calls.
I have already logged #9623 for adding async support to contact-summary code (and we can do the same for tasks/targets). If someone is interested in implementing #9623, I would be happy to support!
