The Automate script on the Hub is nice but turns out to be a time waster when it comes to update tons of sites if those sites contain plugins i.e. from themeforest and other "pseudo-proprietary" sites where you simply can't update those plugins automatically but where you want to update the rest of the plugins. All those have to marked separately per site as "don't update".
I, therefore, have the feature request that there must be a way to copy a master setting for one multisite to all existing subsites in one multisite/multinetwork installation which is using one and the same plugins directory!
There are also other reasons i.e.
all plugins in plugins directory get updated together by one site.
even if you run a template from different "pseudo-proprietary" template sites where the templates also offer their own plugins (which all have to be GPL v.2 by default by the way), all those plugins could be used also on all other sites of a multisite and it does not make sense to have all those error messages on all those sites which don't use that specific "pseudo-proprietary" template.
It would also be very helpful to see the path (domain) where the update would be pulled! and to have the ability to enter an own repository from where the plugins and themes could be updated.
