Artisan items and runes

Qistrel

Can you attach great runes to artisan-enchanted items, like horns and watches?

A lacework of silver is exquisitely formed and thickly clustered around
the middle of this watch to conceal and protect the inner workings. The
outer edges are thin, naught more than thin swirling loops which obscure
nothing. Tiny flecks of obsidian are scattered along the strands, and
only through close inspection can it be observed that these flecks each
have eight legs. The center of the watch's face consists of
intricately-shaped obsidian, a black rose with a pair of obsidian thorns
forming the hands. This face is covered by a thin pane of glass, upon
which can be seen the inscribed shape of a leopard ready to leap upon
unsuspecting prey.
It weighs 8 ounce(s).
It bears the distinctive mark of Talan Ysav'rai.
There is a clockwork charge regulator firmly attached.
It is enchanted with the true time spell, holding 50 charges.
It has been stamped with the seal of The Ysav'rai Kinship.
It has a Great Rune of Bodily Fortitude attached to it (#147842).

Only certain runes work though, I couldn't put an enchanting rune on the watch, so I had to use this one... I don't know why.  Maybe it's been fixed though!

Long and slender, this flute is a long, straight pipe of polished wood,
with several round holes for the fingers lined along one side. A
slightly larger opening, limned with bright gold, serves as a mouthpiece
at one end. Swirling patterns of leaves are etched upon the dark wood
and painted in smooth golden tints, winding gracefully along the length
of the flute. Twin bands of tiny emeralds set in gold encircle either
end of the flute, lending the instrument a touch of brilliance. The
material of the flute makes for a voice is sweet and trembling, and more
whispery than that of most other flutes.
It weighs 13 ounce(s).
It bears the distinctive mark of Talan Ysav'rai.
There is a clockwork charge regulator firmly attached.
It is enchanted with the avarice horn spell, holding 40 charges.
It has a Great Rune of Enchantment attached to it (#138063).

You could always issue it and ask them to expand the options; like I said in my post, certain runes seem to work while others don't.  I was just happy to find any runes that would.

But that's why I gave the exact runes instead of a yes/no answer, because it's more complicated than that.  Unfortunately.

Yeah, can't seem to put my Great Rune of Charity on my horn, hmm. Not sure if it's a bug or not?
