With the May 2020 Release, you can now configure placement fields. This means that you can create, organize, and set mandatory fields you need in the Placement section.
To configure, go to Settings → Field configuration → Placement Fields
From here, you can add up to 25 placement custom fields simply by clicking on a field type of your choice.
PLUS you can organize the placement custom fields into sections if required.
You also have the ability to set which field is to be mandatory.
Note: If your placement field is set as mandatory, that placement cannot be completed without the mandatory fields.
Custom fields can be added as wildcards to documents. To add your custom field as a wildcard, check 'Enable wildcard'. You'll be able to find this wildcard available in the wildcard section in the Document Builder.
Finally, you can export custom fields in the Export Scheduler. 🎉
