Concatenate data column after Refresh

[Anonymous]

I was wondering if you can keep the previous data and add to this data the refreshed data.

I am using an API to get some data (small amount) but I want to update this data every week or so. I found out that I can refresh it with the Power BI web app -> My workspace -> Datasets -> Open Menu of my dataset -> Schedule Refresh. 
This is very useful, but I want to keep my previous data and add to it the newly fetched data. This is do make some kind of KPI based on the workflow of a project. 

In the end, I would like to have a dataset filled with several colum, each column representing a "Refresh" update.

KPI

Best regards,

No, the model will only show the current results.  You would need to pull the data into SQL and append it to a history table then have your model pull from that history table.

Thank you for your response, so there is no "pure" Power BI solution to this? Because we want to avoid using external options like a SQL server or a Python script.

Correct.
