[FFmpeg-user] Change startframe number of DPX sequence?

During ffmpeg conversion of Prores QT mov files to DPX the default 
condition is that frame numbering starts with 1 using and output name of 

When using source qt files containing timecode it is desirable to have 
the timecode, translated into framenumbers, fixed in the output dpx 
files. Is there a flag or property that can be set to force the output 
image sequence to begin numbering at an integer other than 1? I can 
perform the timecode frame calculation myself but would like to avoid a 
"manual" renumbering of the output files after transcoding if possible.
