Data Publish using Gen Flow 2

Hi there!

I'm currently using Gen Flow 2 to publish my data in a Lakehouse. When I refresh the data and click on publish, it replaces all the data in the table, which is time-consuming.

Is there a way to avoid replacing the entire data and instead have the option to either replace or append the data? This would significantly reduce the time it takes to publish the data.

Additionally, is there a way to view only the data that is not already in my Lakehouse and that I want to publish today?

Looking forward to your response.
