not in the current build Hector.
In 6.28 I've added 2 new options to the wizard widget though;
hidePreviousButton
disablePreviousButton
these can be set using loc:options, right before the call to ntwiz. So for example, search the form code for
ntwiz
and then in the embed just before it set
loc:options = 'hidePreviousButton:1'
Cheers
