[Shotwell] Option to KEEP duplicates?

["eabforums gmail com" <eabforums gmail com>]

I started out NOT using a photo manager, and just put all my photos 
under folders with relevant names - "Dinner with Boss", "Trip to 
Durrow", etc.  But as time went by, things got moved around, copied, 
renamed, etc, so I have a lot of duplicates.   Now I want to use an 
actual photo manager, and am trying Shotwell. But when I import, the 
duplicates get left unimported, and hence do not appear in the folder 
list where I expect to see them.   I guess whatever Shotwell gets to 
first, gets priority. Regardless, this is EXTREMELY inconvenient, as the 
folder list is my absolute starting reference point for what is what.

Is there some way to keep the duplicates?  I am totally okay with having 
duplicates in the event list at import, as I will get around to 
creating/modifying events on my own.  During import, the events are just 
dates anyway, which do not necessarily correlate with any particular 
event, or may contain multiple real events under a single date "event".

Or alternately, how can I compile the code to honor the 
"disable-dupe-detection" and #if !NO_DUPE_DETECTION directives? I've 
tried, but it either ignores me or refuses to compile, flagging an error 
about my source not matching the original .tar.xz.  The executable that 
I end up with still detects/rejects duplicates.

Thanks,
