Drobo Access Question

I have a 5N that I’ve used primarily in my house for backup of two Mac computers.

I’ve experimented a bit with Drobo Access, and have been able to access it via the web link, and via my iPhone.

However, I would like to know if it is actually possible to access directly from an app remotely? Specifically, from Adobe Lightroom, which would see it as just another drive location? I can do that in a direct network connection on my home network, but I would like to know if it is possible from outside of my network?
