HELP: Creating a dynamic filter that "ignores" data based on date.

You could add a column to your data that has something like this: 

Column 1 = date(year(now()),month(now()),day(now())+2)

That will return 2 days in the future from whatever the current date is. 

Then add one more column, that compares Column 1 with the Date column in your data.  Like:

Filter Column = DATE >= Column 1

That will return TRUE or FALSE. 

Then just filter your data for the ones that return TRUE from the Filter Column.
