It is possible to import journal entries into Sage using the provided Excel template, or indeed any other template file providing we map it correctly, but such journals are brought into Sage as individual transactions (or at least appear to be so) rather than the composite (which is probably the wrong description from a technical point  of view, but will suffice for the layman who is writing this) entry, which it would be if the journal entry had been set up manually in Sage 50. 

It would be helpful if the import tool asked whether transaction should be treated as a single composite transaction, or we had a mechanism to identify on the spreadsheet used to create the entries, items which should be treated together as composite items, distinguished from items which should be treated individually.
