Hi, After searching through the forums and documentation I still could not find an answer, so I'm trying my luck! I have a custom event that I send when a player has finished a level, and I want to add the status of all the challenges that he's completed, which are stored as an array in-game. For example, the player has won and completed challenge 1,3,5 but not 2 and 4. So I want to send this data along with the game over event - to be able to view which challenges are most likely completed by the game's completion. Is this possible in any way that does not involve creating a bunch of custom parameters (challenge1, challenge2, challenge3, etc...) for sending this data? So far I've created a new custom parameter for each piece of data that I'm sending, and attached that manually to each event that uses that data (for example, levelWin or levelLose both send most parameters). But doing that manually with the arrays would be tedious and not very future-proof... Perhaps using nested JSON object in a string parameter? But then I'm not sure how I would query that in the SQL Data Explorer... The only other way I thought of would be sending many custom events - one for each challenge - when the game is over, but thought that may be overkill...? Would appreciate any help or pointers in the right direction, thank you!
