SharePoint add-ins and Office Store

Question

If i publish one of my SharePoint add-ins in Office Store, would it be possible for me to control who can download the add-in? I mean to target the the add-in to specific tenants somehow.

I know some of the answers would be just to add the add-in in the tenants own App Catalog, and this could be the solution, but I'm still curious about my question above.

My goal is to centrally control the add-in regarding pushing new add-in updates to the tenants using it, instead of pushing the update to each tenants App Catalog.

UPDATE!

Thinking loud, a better solution would be to configure a corporate App Catalog where I put all of my add-ins and then specify which tenants can have access to this catalog, a sort of an own smaller Office Store. Would that be possible?

One of the approaches could be to implement Remote Event Receiver, specifically Add-in Installed (AppInstalled) event and have it dip it in database which will contain the allowed Tenant Ids, Urls. A sample code of the event handler would be:

public SPRemoteEventResult ProcessEvent(SPRemoteEventProperties properties)
{
    SPRemoteEventResult result = new SPRemoteEventResult();
    string TenantDomain = properties.AppEventProperties.HostWebFullUrl.Host;    

    switch (properties.EventType)
    {
        case SPRemoteEventType.AppInstalled:
            if(IsTenantAllowed(TenantDomain))
            {
                result.Status = SPRemoteEventServiceStatus.Continue;
            }
            else
            {
                result.ErrorMessage = "This tenant is not allowed to install this app, please contact [email protected] to get access.";
                result.Status = SPRemoteEventServiceStatus.CancelWithError;
            }
            break;
        default:
            break;
    }
    return result;
}

You need to implement below method such that is returns true if the domain is found in allowed Tenants.

bool IsTenantAllowed(string TenantDomain)
