Allow running a smooth step more than once

Question

I am creating a plugin for Jenkins that adds a new type post post step (Publisher). When I try to create a new task, I can only add my new step once (it may not be available in the menu after assembly). I would like to be able to add it as many times as I like to the same work with a different configuration for each of them (i.e., Different instances of my Publisher subclass). How can this be done, and what does Jenkins say only allow him to be added once?

Update

It seems like this has something to do with the <f:repeatable>jelly element , but I cannot figure out how to use it, and I cannot find any information about it. I tried to monitor the HTML Publisher plugin, but kept getting errors. If anyone can explain how to use this, or point to a link, that would be great!

Finally, you can understand this after much trial and error based on the HTML Publisher plugin.
