Not in Qimage One as Qimage One doesn't have image editing capabilities; it's only for the printing stage.  With that said, I have never found the need to try to "force" out-of-gamut areas in-gamut.  The reason being: those areas will be forced in-gamut at the printing stage anyway and I've not found any consistent way to beat the color management engine at doing that.  Most of the time when you edit an image trying to get out-of-gamut areas in-gamut, you end up adversely affecting other areas of the image that don't need modifying.  By simply choosing perceptual (scale "down" colors across the whole image) or relative colorimetric (only bring the out-of-gamut areas in range with others unaffected), you can almost always choose which look you prefer without trying to use manual edits.  There are rare cases where manual edits would be better to tweak one specific color but in general, you are better off letting the color management engine (profiles) take care of those areas automatically.

I mention this because I've seen some people who feel like they have to edit every image in soft proof mode just to try to get everything (or most areas) in gamut.  If you look at their work compared to just reprinting with either perceptual/RC intents, their manual tweaking is worse 95 times out of 100.

I only use the out of gamut indication in rare cases where a deep blue shirt comes out a little purple in the print or something of that nature.  Then if I check the out-of-gamut colors, I can see why it might be shifted a little (relative colorimetric can do that in color extremes).  At that point, I might reprint with perceptual intent to see if I like that better.  I usually print in relative colorimetric intent unless I see a problem (which is pretty rare).  Then if the colors in question are out of gamut, I might try perceptual intent instead.

I do print on some matte papers including fine art.  They are actually more challenging because they have a lower dynamic range (read less vibrant colors) than semigloss or gloss.  Out of gamut can happen with B/W images but it is typically limited to deep shadows where the ink can't get black enough to represent really dark shades.  That's really a different "kind" of out of gamut though because black point compensation will take care of that.
