Export DGN to PDF in same path that is set by the file

When i export the file and i have to define the path, it opens the last folder i saved another DGN export in. I want the path of the file export to by standard be the same. It does not matter if the solution is defined by a path or is set to open the same folder as the DGN, but we spend to much time always finding the folder with the project in.
