Expand/Collapse Hierarchies in Tables/Matrix?

[OneWithQuestion]

In Excel, SSRS, etc... you can easily use a hierarchy and it will make the table/matrix expandable with little + and - buttons:

Is there still no way to accomplish this with Power BI?

For some reason I was thinking this functionality had been added, but I am not seeing it.

Is it really still impossible to do expand/collapse on simple hiearchy like sales regions or product categories, etc...?

Thanks!
