This Preferences page allows you to view and edit Renaming Sequence parameters.

Rename Sequence parameters allows Corel AfterShot Pro to sequentially number your images while remembering the last number used for specific sequences. Each Jobname can use a unique sequence, or you can use overall sequences like the [seq] renaming variable. The Value column on this preferences panel shows what number the next use of each sequence will use. You can double-click the Value cell to change the next sequence number.
