Thanks for your patience. I would need to take a closer look at your site. So I would need to request temporary access (WP-Admin and FTP) preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed
Your following answer will be private, which means only you and I have access to it.
✙ I would need your permission to de-activate and re-activate Plugins and the Theme and to change configurations on the site if required. This is also a reason the backup is critical.
I've tested this on our dev site and it looks like what you needed there isn't something that is currently possible to achieve out of the box using the available options. I will check this out with our 2nd Tier Support to see if there is a way to achieve what you need there.
