Adobe -CRM integration - templates attachment

Hi,

I attached a couple of documents (Doc A - 1st attach file, DocB- 2nd attach file - order sort small to larger) to the Agreement Template in CRM. When send out for signiture, it Merge 2 documents to 1 but DocB shows before DocA.  Please advice how to make it show DocA then DocB.

Thanks in advance.

Best,
