7-Zip command to extract filenamepart before the first "."

Most .Rar files have a few "." in it, like for example "Movie.part01.rar"

With the following comand just the part after the last "." is
excluded.

"T:\Tools\7-Zip\7zG.exe" x {filepath$} -o"{sourcepath$}{dlgstringS|Foldername|{file$|noext}}"

So in the example above it will extract to "Move.part01"

Is there a way to extract just the filenamepart in front of the first "."?

I don't think there's an easy way (without using some VBScript or similar) to remove two extensions from the names. (It'd go wrong for single-part archives that had two dots in the name, too.)

Might be easier to create a button/hotkey which removes ".part01" from the folder name, to be used after extraction.
