I have a similar need for a note type area and have increased the Caption size to 15 lines so that I can copy and paste online results or other digital info to the area below the automatically ingested basic caption.
An example is attached of the space that is available using 15 lines. I had previously used 18 lines but it was unnecessary. This is the basic variable that is used for ingesting:
{city:UC}, {cnty:UC}, {mnn:UC} {day}: during the {objt} at the {loc} on {imnn} {iday}, {iyr4} in {city}, {cnty}. (Photo by David Finch/Getty Images) *** Local Caption *** ;
And this is the result before the caption is finished:
DUSSELDORF, GERMANY, FEBRUARY 25: during the 2017 Dusseldorf Grand Prix (24-26 February) at the Mitsubishi Electric Halle on February 25, 2017 in Dusseldorf, Germany. (Photo by David Finch/Getty Images) *** Local Caption *** ;
The space is particularly valuable when I need to put the full four medallists into the caption. Obviously, the info once used is deleted to finish the caption. It definitely makes life easier and quicker to have those few extra lines.
