I need to deploy a NAL app to all users in the tree, spread across more than 325 User containers

I created the NAL object, and associated .networks.users.ho to it (the container I am in) and it works, but is there an easier way than adding the 325 user containers as associations

I tried adding o=ho as a association to the object, but then the object does not show up. Even one level up from the .networks.users.ho container, aka .users.ho as an association does not work (Application doesnt appear in NAL)

Please assist? I have to have this rolled out today
