ISO Week of the year in time series when using GA data is not available. Only available in Bar chart
When using Google Analytics 360 as source I'm able to create bar charts using ISO Week of the Year as dimension and sessions and transactions as metrics. When trying to do the same with time series charts I can only pick Week of the Year as dimension using the same metrics. This is of course suboptimal. Is this a bug or being worked on? To me it makes no sense to have ISO Week of the Year in bar chart and not in Time series.
Please fix/add this.
