JaeAnn,

Your reply would be great, if I only had one check to write.  However, I do not write just one check at a time, i.e. I go to Vendors>Pay Bills and mark 20-30 Vendors to pay.  I do a check run every week (20-30 checks each week).  In QB Desktop, I was able to choose which and how much of a particular vendor CM I wanted to use, while in the process of marking ALL of the payables, I was going to pay on that Check Run.  Is this not possible to do in QBO?
