Location Tracking - Custom POI file

Currently, if you want to manage your points of interest for Location Tracking, it is recommended that you manage the information through Mobile Services using the interface or by uploading a CSV file to that location.  When you view the line in ADBMobileConfig.json for analytics.poi, it points to a file that begins with "https://assets.adobedtm.com/.../<fileName>.json.

My questions is this: Can I point to a custom file of my own sitting elsewhere, or am I required to use the location shown in my config file.  The goal for having an alternate location and/or file name is to maintain a file that updates automatically instead of being required to upload a new file anytime the information changes.

Thanks in advance!
