How do I propagate a specific module (not, for example, all HTML Custom modules, but only one of that "category") from Master to Slaves?

I succeeded in propagate a module type to children but not a specific module.
Thanks.

First the installation available in the JMS tool menu is used to INSTALL the extension (components, modules, plugins, templates, languages).

The objective is to install missing extension and not the setup of a module.
The objective is to have the module declared in Joomla to make it available in the list of modules of the slave site. After that, you have to go in the slave sites to setup a new module instance DATA at a specific position.

The propagate action consists in repeating the installation process in each children websites (tree) under the slave site where you install the extension.

Therefore, when an extension is already present, it is not installed.

An additional feature is the "overwrite" check-box that allow trying to overwrite existing entries to replace their content.
The overwrite does NOT synchronize the website. It does NOT delete records that would be removed. It just use the "REPLACE" MySQL statement instead of the "INSERT" statement when processing the extension.


So you can NOT select a specific "single" module configuration from a website to setup the "children" slave site with this particular module.
