Under-reimbursement of taxis etc.

The automatically calculated reimbursement totals only cover approved amounts. Which doesn't apply across expense types.

So, if someone was approved for 900 EUR for flights, and spent 800 on flights and 100 on a taxi, we'll only reimburse them 800.

I will probably just allow approved expenses to be applied across categories. Maybe with some cut-off percentage?

This will require a review of previously completed reimbursements and probably some follow-on top-ups.
