v2.9.4 syncs ALL themes in multisite network

I’m running a multisite network with over 75 sites, all with their own themes. I activated BH Turbo CDN on one site, and when I went to sync files, it scanned and began to sync all the files & assets for all the themes and all the plugins (even those that are not network activated or activated on the one site) on the network. That’s A HUGE NUMBER of files that I do not need synced for this one site!

I looked, and I think the plugin is not trying to sync images, posts, etc. from other sites. That’s good, but how can I get it only syncing the files needed for this one subsite?

Each site on my network is domain mapped with it’s own non-subdomain domain name. I’m assuming that to let Blue Hat do it’s work most effectively, I will need to activate Blue Hat individually on each site, so that the urls for files don’t have to be redirected. But if each subsite syncs ALL the themes & plugins, that a HUGE redundancy in storage and data transfer costs.

Is there a setting to control more carefully what a multisite subsite syncs?
