Im trying to add some already existing data, to the context of adding new content. Im trying to get the list on the first image called "Attributter" to be preinserted into the second image "Attributter" context when i click "Add Sammenlignings-element". But i can't seem to find a way to actually do this. The list is supposed to be a predefined lidt of attributes, that will be added automaticly to any new object created, just so the editors wont have to manually add them. Hope this makes sence 😄 https://cdn.discordapp.com/attachments/1220310362667352134/1220310362851643403/image.png?ex=660e7996&is=65fc0496&hm=87649aeb7e3a0dbe17ca1791eb32730cf1abe9b746d42130d6bd6cf2d42f5f27& https://cdn.discordapp.com/attachments/1220310362667352134/1220310363078397972/image.png?ex=660e7996&is=65fc0496&hm=dd8f508531159ee98d7fc2d20896e0d3d40e1b100bd3208ab0b5a436cf02b47b&

> The list is supposed to be a predefined lidt of attributes, that will be added automaticly to any new object created I presume this isn't always the same cause then it's not really content. But more that it is the list of most common used ones. You can use the SendingContentNotification to intercept the data that gets send to the frontend, you can use this to setup default values. @Poornima Nayar wrote a blogpost about this for v9 https://poornimanayar.co.uk/blog/umbraco-9-editor-model-notifications/
