HI mnik ,
Ok, got you thanks for clearing this out for me.
Well, all the features mentioned above are part of our Multi Inventory premium add-on. Regarding reports, there are now possible to achieve using our Export PRO premium add-on, where you may need to complete the work by editing the exported file.
More advanced and automated COG premium add-on is planned for later in the dev stage (2021).
Hope that helps.
Pavel
