@dserafin - For something in the meanwhile, this is what I do to get reports:
- Added custom field(s) to Maniphest Tasks to classify task type - see Configuring Custom Fields
- Install extension for exporting Maniphest Task search results to Excel spreadsheet
- This requires PHPexcel to be installed on the machine, and for your php.ini to be configured to load that library.
- The extension can be downloaded here (use at your own risk) - this adds some columns to the output to include some custom fields -- not all field types have been tested/implemented. If the task is on a project workboard, it will also list the workboard columns it's on. The code is fairly straightforward so you should be able to modify as-needed.
- From web interface do a search query for tasks, then at bottom select Export to Excel, then select the 'Default with Custom Fields' option.
