I am a Trello Gold user and I have a Trello board in which I use the Custom Fields power up on the cards. In this case, I use the Custom Field - Dropdown List, in which I have registered 50 options for choosing the card user. However, when trying to register another item in this same drop-down list, the option to insert the new item does not appear. Account upgrade is required to add more than 50 items to the drop-down list Thank you very much in advance. Thanks
