Reuse a line or a block of text without creating dummy code

In Doxygen, how to reuse a line or a block of text?

Suppose I write the following in some file:

/**
 * \magicCommand{magicLabel}{this is some text that I want to show.}
 */

Then, when I write the following in another file,

/**
 * OK, \someRefFun{magicLabel}
 */
void f() {}

Doxygen will create the following in the html document for f():

OK, this is some text that I want to show.

I see @copydoc can do something like this, but the problem is that I would need to create some dummy function for the referred text to depend on. Can it be done without using a dummy function?
