This is a feature I've been missing in ardour for quite a while. yet an
easy workaround is to batch search&replace "<Region [^>]* name=XX [^>]*
position=" in the .ardour session file.. ;)

should we make a feature request out of these:
  * popup-dialog to edit start/end/duration time of a region
    (calc shift,offset to/from clip, reset region to clip-values)
  * move region to default position on right-click-menu
  * insert clip as new track using default position
  * popup-dialog to set/edit the default position for a clip/source.

ardour meta-data has always been some kind of pandora's box, Could you
guys comment on the use-cases and user-interaction before we ask to add

The default clip-position could come from an audio-file header or when
recording audio from jack-transport..

sorry I've cut most of the original thread.. see there.

This will only solve the user-part. ardour still needs to know the
/default/ timestamp. nowadays most pro-equipment digitizes LTC early
using hardware converters under the hood.  Modern audio-formats have
more practical means to exchange time-stamp/timecode information than LTC.
