Right now: you do have to remeasure the first 2 pages if you want to  
build a profile
from only the 225 patches without the extended grays. There isn't  
currently a way in
the software to convert a 4 page target measurement set into a 2 page  
set.

If you're not satisfied with the profile you're getting from the 4  
page measurements,
however, that's more likely to imply that something else is wrong (you  
may have
printed the target incorrectly; or you may have performed the white  
calibration
on the spectro incorrectly; or there may be something wrong with your  
measurements;
any or all of these). Measuring and including the extended grays (the  
last 2 pages
in the 4 page target) shouldn't do anything more than make your  
profile more accurate
around the neutrals; it shouldn't give you a profile that's "worse" in  
any way.
