use time from filename as exposure time fallback
Please describe the problem you are trying to solve
exporting pictures from messenger apps like signal results in an empty exposure time, and therefore such pictures are not assigned to a specific event.
nevertheless, the filename of the exported image contains the needed information: for example "signal-2023-09-17-184120_002.jpeg", i.e. "signal----....jpeg.
it would be great if i could define patterns which get checked against the filename of the file to be imported. the extracted date could be set as a fallback exposure date if no EXIF/XMP/IPTC metadata exits
Other solutions you have considered
an alternative would be to use a script to crawl all files, adjusting the exposure date (if empty) from the filename. unfortunately, for many desktop users this may be no viable solution, therefore an integrated solution would make sense
nevertheless, thx for your great work! hari
