R-based visualizations have Row and Column Manipulations sections which allow you to set the "Number of rows from bottom to show", for example. However, for non-R-based visualizations, the closest we have is the "Show a Range of Rows" rule, which forces you to specify the start and end range. Having a built-in rule which does the reverse of the "Show Only Top K Rows" whereby you only need to enter a single value is a better workflow.
