    Hi Biagio,

    Yes it is possible, though perhaps not as elegantly as you would like.

    There are two steps to solve this:

    Step 1: You need to prefill the name field with a non-empty string. Something you can distinguish later in your code. I usually fill the name with a random guid. You can do this, by listening to the SendingContentModelNotification using a notification handler.

    Step 2 You need to handle the ContentSavingNotification. Check if the name of the content is the name you specified in step 1 (a random guid in my example). If it is, read values from the content model and replace the name.

    Also don't forget to do a check on the content type so you only perform your logic on the correct content items
