Remodeling the data from columns to rows based on timestamp/date

Hi everyone,

I am an medium expierienced user of Excel but quite new to PowerBi. 

I am trying to solve a problem which I suppose will require remodeling the data but I am completly lost and search for advice on how it can be done (if it's possible) 

This is how I currently have data in Power BI.

And the table I am aiming to transform into it should look like this one: 

The initial goal of doing this transformation is because I have to perform a COUNT on each date for a specific tag name "Name1" to see how many times that tag firied in a specific time frame. 

If you think it's easier to adjust the COUNT to those many columns instead of changing the table I am completly open for suggestions.
