Create a microflow that creates all those objects. You could take a look in the Country Enumeration module for instance as an example.

You can create a MF which creates all those objects.
The best thing to do is to call this MF as a SUB MF on the AfterStartUp MF. See this link on how to use the AfterStartup MF.
