Ok.
If you are going to upload file manually every time you need to aggregate, then you can merge the files and upload them as a single file, you can do manually or use some custom PowerShell or Python or any other script of your choice.
But don’t you think, if there is a way to aggregate CSV files automatically without manual intervention, it’s cool rite.
Yes, We have solution for that as well. File Upload utility, refer to below docs for more information.
