Date Filter -- allow users to only choose a value from list of days

Hey sylvia_gulubova ,

Date Filter allow different Granularities such as Years, Quarters, Months, Weeks and Days. 
In Version L2024.1 the New UI Filters are enabled which provide different view as the screenshot shared which using the old filters UI/UX. 
In both cases, using the Dependent filter will allow switching the Granularities which isn't sufficient in this case. 

I would refer to the second option which is creating a blox drop down filter that allow a single select for Days.

1. Create a Blox widget and Add the Date Column with Days granularity. Please find an Example.
2. Add the Date as dashboard filter and Hide it
