Is there any way for IFTTT to monitor nested folders (i.e. subfolders) in Dropbox as oppose to top level folders?The google drive IFTTT integration appears to offer this capability, but I can't see you can do this with dropbox..

Yes, the Dropbox API certainly offers the ability to access and monitor nested folder/subfolders at any depth. (For example, /2/files/list_folder[/continue] can be used to access any folder level, and also offers a "recursive" option. And Dropbox webhooks notify of changes at any depth.)
I can't speak to what functionality IFTTT has or hasn't implemented though, so you may want to contact them to ask about it.
