Digital BW, The Print

Just a heads-up on Lightroom Beta 2 -- all of my custom greyscale ICCs no longer appear in 
the dropdoown when I choose 'Profile > Other...' instead of the default 'Managed by Printer' 
under 'Print Job Settings'.  The read me included w/ beta 2 has this to say: "Lightroom 
supports only RGB custom profiles for printing.  ICC profiles which convert colors to CMYK [b]
or Grayscale[/b] do not appear in the Custom Profile popup in the Print module..."

Probably fine if you're on a 2400 using ABW, but what about 'the rest of us'?  Kind of a 
bummer, unless I'm mis-reading or mis-using this bit of the app.  I've posted a similar 
heads-up on the Lightroom beta forum.
