You can choose to have different approvers depending on different traveler custom remarks.
Because travelers may be required to fill in additional data at the time of booking, for example, project name, this will allow defining who the approver will be for any traveler that will fit those criteria.
Determine who is the default approver, which means they will approve when a traveler custom remark doesn’t have a specific approver. The default approver has the power to override the minimum approvals needed. For example, if a level has 2 minimum approvals and non of the remarks created apply to that traveler, the default approver has all the power of approval of that level.
Then, click on the plus sign and determine who is the approver, what is the remark, and what is the value for that remark. In the example in the image, any trip by a traveler who works in the sales department will be approved by Joana Doe and any trip by a traveler who works in the marketing department will be approved by Maria Doe.
