I'm building a 3D calendar system for AR/VR, and looking at using Playfab for the backend. I'm trying to use something akin to an inventory management system for storing a user's events. Playfab seems ideal as it handles authentication across platforms, although it doesn't seem as friendly to the idea of a user being able to edit objects in their inventory. I also want to be able to duplicate, and then modify groups of event objects. I've been exploring the user publisher data, entity, and item catalog systems, although none seem to call out as a solution that meets these needs super well. Can somebody more familiar with these systems please point me in the right direction? Thanks!
