Group reportings by tag

[IHappyDayI]

Hi,

Feature Request:
Allow the user to group their reportings by tag (and create an export grouped by tag).

Here's my use case:
I track my time at work based on projects and tasks. That is important for the business/billing of customers. However, to track what type of tasks (independent of projects) I spend my time on, I use tags. For example I want to know how much time I spend in meetings or how much time I spend on research topics, etc. Currently I can track this, but I can't find a way to get an overview/export based on these tags.

The group by drop-down is missing tags
