What is the desired functionality that you are missing?
As an Optimize User I would like to be able to choose a custom delimiter when downloading reports as CSV.
Which problem are you going to solve with this functionality?
Today the default delimiter is "," but in many situations this delimter is problematic, especially when exporting RAW data reports that include variables and the variable values include "," as well. This breaks the parsing of the CSV. Therefore it would be useful to be able to choose something custom if needed for a specific report.
Hint: We could consider to make this a system config for now.
