Dynamically change data by date range slicer

Hello. I'm trying to find a way to dynamically change my data by using date range slicer.

Here is a simplified report per one unique ID:

and below is an output I get when using the date range slicer:

I have a Member ID, Number of Events and Event Date columns. I would like to add a dynamic column that would count number of events by date range slicer to the right. (Date Range Slicer is using a same column as the table)

Essentially,I would like to add a NewColumn(calculated) or a measure that would be dynamic and also removed Event Date column so that my outcome would read only 1 event as below:

Member ID  Number of Events   NewColumn

977428        2  Events                  1

In other words,number of events = total number of events and NewColumn = Number of Events by the date Range slicer
