Hi Marcia,
By default, there is no connection between the FileContent and Pipeline file browser areas and the Lists.
If you need to upload a CSV file to your specific List, you should use the Import Bulk Data option on your list and upload the CSV there so it can be processed and added to your list.
It might be possible for you to develop your own pipeline module to try and have the system process it, although people usually use a pipeline module in conjunction with assays usually:

It also might be possible for you to leverage our APIs to process your large CSV file as well so it can insert all the individual rows from the CSV file to your specific list:

However, the easiest option would be just to use the Import Bulk Data option within the list to import the data to the specific list you want it to be in.
