CSV import: Table with headings

Is there a way to tell DTPO that the first line of a CSV (or TAB-delimited) table contains the field names.

If not: Can I somehow show the field names in a table instead of A,B,C, etc…?

Over here, the first lines of imported .csv files are converted to headers. Be sure that the file is a plain text file. In Preferences > Import check “Tables and Sheets…”
