upload target with JSON from the application to VuforiaCloud

Hi, I have a program that uses augmented reality to overlay images when it detects a certain surface. I do this scanning of targets using CloudRecognition and VuforiaCloud. You go down the street seeing the environment and when it finds a target it is able to know from which location (https) it has to download the image to be superimposed and where to superimpose it. It achieves this thanks to the fact that in VuforiaCloud I have an associated JSON that indicates various parameters. I want to include a functionality to the application, the possibility of uploading photos to VuforiaCloud with their respective JSON, so another person who has the application can go down the street and see in augmented reality something that I or another user has uploaded to vuforia. Could it be done or do I need an external application that does all this process.
