Exporting same tracks from Cubase to VST Live

Hi team.

I have a project with 2 tracks in Cubase and I use the feature “File > VST Live > Export Project…”.
Both tracks are exported and saved in my folder.

Now I need to modify my tracks. So I have my both modified tracks but with same name.

I export again the project > the 2 tracks are not exported because I supposed that the files with same already exist…

But I need to replace this modified tracks.

I do the same and it works partially. Export media project in cubase overwriting the existing or rename it.
If i import the media-project in VST-Live again (and choose the right buttons in the import window) - the files are imported BUT make allways a new song. Awkward but i found no other way.
