Hi @dennba, welcome to the community, super glad to have you here!
When it comes to copy paste in general, you are able to copy a line of text and paste it inside infinity in order to create an item, the line of text copied will act as the name of the item. However, when it comes to copying whole rows or specific cells that are for different purposes (date, phone, email or similar) -unfortunately - that is not yet available, and as @micck suggested we do have our roadmap where you can see exactly where certain features are and in what stage.
Hopefully we will see other improvements to the copy/paste rapid item creation in the future.
