Manually adding old packs

[lessnik]

Great plug-in, but I just recently learned about it. I also play relatively recently, just a year, and used to keep statistics on the PityTracker (do not consider it for advertising). I would like to transfer my past statistics to the base of the plugin. Of course, the cards themselves do not recover from these data, but at least statistics on the chances of loss. I ask to add the possibility in manual mode to enter information about previously opened packs, indicating only the value of the dropped cards.
