Hi Anant,
You can always create a custom metric in screener and use the Minimum function and put days as 5000. See screenshot:

But this will not help you to find this for a particular stock since we do not support custom metrics for each individual stock. We will be adding support for this soon.
But since you are a Black Annual subscriber, you can email us all your data request and we will send you the data you need within 24 hours.
