unfortunately not yet.
I know that you and others have wished for this for a while,
and I had intended to provide it for 5.3.4, but did not get to

Let's aim to have it for 5.3.5 ....
I'm trying to set up something which uses new variables
ess-pref-pdfviewer and ess-pref-psviewer. 

For pdf it would try to use
	1) ess-pref-pdfviewer  -- if defined (is not by default)

	2) getOption("pdfviewer") - if that's a valid file 

	3) revert to the current list of proposed defaults.

Can I send you updated
ess-cust.el and ess-swv.el  and you try ?
