Numbering options are configured in the table management options:

  • If the selected numbering option is "Free," you can enter whatever you want; the label will use that string of characters.
  • If the selected numbering option is "1,2,3," you can enter only numbers. They do not have to be in sequence.
  • If the numbering option you choose is of the "A, B, C" type, you can enter only a letter. The letters do not have to be in alphabetical order.
  • If the selected numbering option is of the "A1, A2, A3" type, you can enter a 2-character string. The numbering will increment by 1. However, if you enter "B1" at any point, the numbering will no longer follow this new letter. You will then need to manually enter "B2," then "B3," and so on...

Between each extraction selection, you can enable or disable filters or change the selection type.

Throughout the selection process, you can reposition the guides and the table.
