Hello,
You should be able to insert rows in the sheet then drag down formula for the expenses type pick list and VAT calculation. Here's an example:

The expenses form isn't attached to the rest of the package, you need to manually add entries in purchases for the expenses and current account for reimbursements. It usually help to summarise the data when copying into Expenses and you can do this as long at the items share a category and you total both the VAT and Gross.
Thanks,
Antony.
