I don't know of a way to actually add topics in the way you
describe and doubt it can be done.
On my site you will find a topic about customer links. Using
that you can have one link in any or all of the topics. Normally
not visible but seen when a javascript file is completed. The links
would point to whatever is required. They would be set up by the
System Administrator though, not the ultimate end user.
There is a program called KnowHow, described on my site, that
might help.
