Thank you Itai,

I do have a Pro Subscription, but everything I see on that page is about how to 'Upload' a file into the system.  

What I am interested in, is a method to load a data file that is supported by the Upload feature, directly from the URL specified.
As far as I can see, I have to download the file from the website myself, and then upload it to Alpha.
I want to refer to the URL, and then have Alpha pull the current data in that file to the Data object directly.

The problem is that the data in the file is being updated over time, and if I pull a file down and then upload again I may be missing what is in the file when the functions are run in Alpha later.  This is not super useful for a cloud application, as it requires a local storage space to download to and upload from.  If I want to create an app out of this function that I am building, I want it to work regardless of the hardware that I am accessing the app from.  I can't imagine downloading data to my smartphone and then uploading it again just to see an updated scatter plot of the data.

Regards,
