Yes, we can. We may export the Custom Labels, created in MapInfo Pro, using the Labeler.mbx tool. We can transfer the custom labels to a table using the Labeler tool it will create a new table and will add a layer on the map in MapInfo Pro. Then we can clear the custom labels and upload the map using the Spectrum Map Uploader. The end user will be able to see the label layer uploaded on the SSA map.
Please, take care to export the label with Labeler.mbx at the correct zoom level as they could appear bigger than you want. We suggest to export at a zoom level less than 50km but it depends on the request.
