Overwrite dialog showing the available options (no overwrite by size)

SUMMARY

There are times when coping files in dolphin that it finds files with the same names and asks the action to take. The overwrite options available are "Overwrite" and "Overwrite Older Files". This is great until you are copying files and midway the operation stops and you have a half-written file, you either have to recopy everything or risk having a half copied file as it will match on dates

STEPS TO REPRODUCE
1. Copy a directory to an empty location
2. Copy the same directory over the previous destination
3. Cancel midway copying a large file
4. Will ask action to take

OBSERVED RESULT
There is no option to overwrite by file size, to allow only overwriting the half-written file and missing files

EXPECTED RESULT
Overwrite by size, so that one does not have to recopy everything

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Manjaro
(available in About System)

ADDITIONAL INFORMATION
Given that dolphin first creates folders, tracking these half-written files then becomes impossible especially for large file sets
