No, people ran into too many problems using the portable version; there never should have been a portable version in the first place. If you build it from source yourself, you could use that as a portable version. Right when you build, you'll go to the folder that is called "app.publish" and in there should be a single exe that you can use for your needs.
Edit: Although, note what you would get from that isn't a 1 to 1 feature parity with what's being prepackaged together, you'll probably run into some crashes, there are extra things you would need to change in the code or build other projects to create what's pre-packaged. I just want to set the expectation very clearly.
