Yes, there is!
The player, after creating the character, must press the Save-File button on the upper bar in the character sheet module.
This will download the file with the browser.
The player should get this file (most browsers will send it to the Downloads folder), and send it to the GM.
The GM should open the character sheet module, click on the Load-File button, then choose the character received.
Then, the GM must press the Save-Server button (the one next to the Save File button).
That will add the character to the application database.
From then on, the character will be available in the adventuring module.
It may be obvious, but: both GM and player should have the same add-on packages installed.
If the player were to choose a race, profession, etc, not available in the GM installation, it will fail to load.
Let me know if that worked for your group. And thanks for the question!
