The main way to do that would be to pack the project materials and save them to either Cyberlink cloud or Google Drive. Obviously you'd need wi-fi/internet access when uploading/downloading, but once that transfer had finished you're free to continue editing without any connection to the outside world.
To intercept the packed project and transfer it to a USB drive, you'd need a third-party "file manager" type of app that could find the cloud drive's temp/cache folder, then transfer the contents to the USB drive and then to the same temp/cache folder on the other device. I don't know how difficult that might be or what kinds of permissions and syncing issues might come up, though.
You might want to let Cyberlink know that you'd like to see a local (USB, BT or NFC) project transfer option. Go to Settings > FAQ & Send Feedback in the mobile app.
One important limitation is that the mobile app (on your phone & tablet) can work with the same project files, but once you import the mobile project into the desktop version and save it, you can no longer open it on a mobile device.
