Manual stand hour for past day on Apple Watch?

Hello,

My Apple Watch did not calculate the stand hour properly. Usually, before going to bed I check my rings and if there’s anything missing I do the workout and close the rings. However, day before yesterday I missed to close my stand ring, even though I stood for close to 14 hours. Is there a way to add them manually for a past day? Please note, I have tried manually adding a workout for the past day but it didn’t work. I just want to maintain the streak.
