Hi @AlexJJ ,
May I know you are acting as a end user or expense approver or expense processor?
If:
1. You are acting as an end user -Technically it is feasible to add a checkbox once you reviewed each expense entry before submitting your expense report. However, this would require small configuration change, and it will be completely your company's decision whether they want to do this change.
Alternatively, I would suggest using existing 'comment' field rather than using separate checkbox field. While reviewing your expenses one by one, you can keep updating some text (such as reviewed/checked) in comment field and save so that you will be sure that all expenses are reviewed.
2. If acting as an Approver or Processor - There is standard 'Reviewed' field is available on each expense entry form which is usually modifiable for the processor and if required it can be kept modifiable for an approver too. You can use this field and update as 'Yes' once expense entry is reviewed.
Note - this field is 'hidden' for the end users as they are acting as a user/expense report creator.
If this answers your query, then please mark solution as accepted.
