Incorrect formatting in the exported data

Hi Piwik Community,

First of all I would like to say Hi to everyone on this forum.

I have a problem with the Piwik. Namely, Excel does not format properly number values in the spreadsheet when I try to export data from the out of the box widget - Visits Overview (with graph). Please have a look on the attached image.

I know that the problem is that Piwik generates numeric values with the “.” as a decimal separator and I have set “,” in the Excel as a decimal separator.
I would like to ask you if there is a way to fix it (I do not want to change my Excel settings)? Maybe this decimal separator can be set somewhere in the Piwik settings? I have to mention that I cannot make changes in the Piwik core. Do you know if this issue is on the roadmap of the Piwik team?
