embed a macro inside a ROOT file

Dear ROOT experts,

Is it possible to embed a macro inside a ROOT file? The idea would be to provide a single ROOT file with data and some macro to visualize that data in one place. The receiver of the ROOT file opens the TBrowser, double-clicks on the macro and say, gets three different histograms nicely colored and plotted on a single canvas.

This could be possible by adding an execute method to TText perhaps?

Cheers,
e.
