Hi,
Analytics Workspace Dropdown feature currently needs the specific values to be dragged on to the dropdown to show those filter in reporting. This may result in manual update to the dropdown values frequently when new dimension values are available in reporting. Request is to have an all values dropdown that can auto populate new and existing values with one drag and drop when initially creating the dropdown. This would have saved everyone's life a lot better.
Please reachout if you need any additional details or questions.
Thanks & Regards
Abraham
