Fellow Forum Members,
Word 2007 has the following letter numbering flow built in:

a.
b.
c.
(skipping d. through t.)
u.
v.
w.
x.
y.
z.
aa.
bb.
cc.
dd.
ee.
(skip)
zz.

Is it possible for WORD to follow the letter numbering format shown below instead?

aa.
ab.
ac.
ad.
(skip)
az.

In other words the "a" stays the same until "z". After "z" is reached the format changes to:

ba.
bb.
bc.
bd.

Then after "z" is reached again the format changes to:

ca.
cb.
cc.
cd.

This numbering scheme doesn't seem to be included in WORD 2007. Is it possible for WORD 2007 to some how support this numbering format? Any info will be greatly appreciated. Thanks.
