Set end date for a medicine on Health?

I was using an app called Pill reminder, but i think that from now on, i will use the health app to put all my medicines and there reminders etc,
everything is working, except that there is no way to insert an end date for a medicine, anyone has an idea on how to set an end date?
I can set the time, date, day intervals and so on, but til what will i take this medicine?
