是否已經有這個功能，或者可以開發一個功能，讓用戶可以指定不再使用的裝備？
應用案例：
一個 session 所使用的裝備條目包含了所有曾經擁有的物品。如果只顯示用戶仍在積極使用或擁有的裝備（衝浪板、帆和鰭），會更方便。
舊裝備不應該被完全刪除，因為統計數據仍需要這些信息。
再次以英文說明 
Is there already a way, or could a way be developed, to indicate when you’re no longer using equipment? Use case: The entry for the equipment used for a session includes all the equipment you’ve ever owned. It would be easier to only display the equipment (boards, sails, and fins) that you’re still actively using or own. Old equipment shouldn’t be completely deleted, as you’ll still need it for your statistics.
