set an end date for a medication on the hhealth app

Hello all:
Am using an app called Pill reminder to remind me for any medications, but am thinking of using the medication feature inside the health app on IOS 16,
does anyone tried it?
i was surprised when i can not find an end date for a medication, all things were ok, except that there is no end date for a medicine.
so, is there a solution for this? or apple will fix it or what?
