It's possible for users to make an unlimited number of Custom Fields. However, when making an email and clicking Insert Contact Details, the list of possible custom fields is limited to only 40. This makes it very difficult for us as we have many custom fields we use to send unique playtesting codes to our game testers.
Please expand the list to include all of the custom fields.
Additionally, the list is not in alphabetical order, making it difficult to sort through even if the custom field I wanted was buried in the list.
If possible, please let me know when this is updated, thank you!
