Load PAWN information via XML in Level Editor

Hi there,
Wanna upload pawn info directly from an xml file once game is being launched (ex. current pawn location or so). Obviously that’s an already compiled client’s work to do so, but I wonder if there’s a way I can manage this to upload the info right in an UnrealEditor’s tab.

Is there any ready-to-go guides on how to change UnrealEditor’s source code, so it’ll be uploading pawn info from an xml file in a current scenes or is there any other easier ways of doing so?

tl;dr or didn’t catch the point:
