Timeseries comparision in dashboard

Hi, guys, I see a lot of similar topics, but cannot find if timeline is set for the feature
I have for example dashboard with the diagram of sales in the year period grouped by month.
And I need to compare to the same months year earlier.
Will be perfect to have it in the same diagram by just button pressed.
Not to create infinite number of models.
Is this feature planned?

You should be able to create these kind of charts pretty easy now with the Offset function:
