Hi Renate thanks for posting on the community! That is correct if you are using data linking you can drag a cell or a row to a shape with existing data and it will prompt a pop up that will allow you to replace the data associated with the shape or keep both. Below is a gif in which I drag out a row to a shape with existing data associated with it and opt to keep both the old and the new data.

If you are not seeing this pop up after following the steps as outlined in the gif above please submit a ticket using this form and include a screen recording of what happens when you drag the new data cell to the shape as well as the doc URL so that we can take a closer look. 

For anyone else that has questions about data linking please check out our Link Google Sheet Excel or CSV Data To Lucidchart Diagrams article.
