Filter only on one of multiple values in one chart

I created a line chart with two of the same line values (sales). What I would like to achieve, is to show two different values of sales within one line chart: 1. general value (the whole company, unfiltered) 2. value for a specific region (filtered) The specific region should preferably be able to filter by a slicer or level filter. If found no way to achieve this in Power BI. Is this possible? I use a live connection to a cube, so MDX is not possible, but DAX should be possible in the future.
