How much task it would be if I would program this functionality fo
TV, instead of colpos, the name of the field could be stored
for example to the field 'tv_field_name' to 'tt_content' table.
Maybe it is quite difficult to get the field name from the flexform
and store along each content element.
Maybe there would be serious update problems.
But it would be fine if this would possible.
