revBrowser: simulate textSize property?

[sp27]

The available properties of revBrowser that are listed in Dictionary under revBrowserSet do not include text size. When my user clicks a button that calls revBrowserMakeTextBigger or revBrowserMakeTextSmaller, I would like to store his preferred size choice and use it when the next instance of the browser is called.

Is there a way to do that?

Thanks,
