Dump-Checker Button "Check all" at the start

[wellemut]

Usecase

I have 500 entries, and most of them exist already on the map. But I want to import especially those, who are still missing. Before I do the individual merges, I would like to see, which of them are easy to import without any duplicate warning.

Problem

Klicking each entry to the next dialog, only to see, that it exists already is quite annoying

solution

• Can we put a button on the first page "Basic duplicate check" where we use the dump-checker to check the whole list
• Instead of the red ? it could show directly the number of possible duplicates
• The list should be grouped by "new imports" and another section "duplicate warnings"
• For the list "new imports" I would need a button "import all"
