Is there a best practice on how to create a centralized help contents that get propagated to help xml files?

We have a bunch of functions that uses a common set of parameters. When we change the help of a parameter, we don’t want to change several xml files. We want to change just one file and run some build function that would take the new content and apply it to the xml help files of the functions that use that parameter.

Is this possible?

Thanks for the guidance.

Per Dougs recommendation to me some time back, I can vouch this module works very well. I had over 60 functions to convert to HTML. Used this to get them to markdown, then to HTML from there.
