Is there a way for players to create and export a combatant entry for their PCs and send the file to the GM so that the GM can import it into InitiativeTool?
What I'm hoping to emulate and improve upon is the use of The Game Mechanics' Initiative Cards, which allow me to distribute blank player cards for them to fill or update and return to me with all of their information. They usually update or fill the cards before each game session, and transferring what they filled out on the card to Initiative Tool would take way too much time. If they could fill it out in InititiativeTool and send me a file to import, that would save a lot of time.
Importing/Exporting Combatant files
There isn't an import/export feature but there isn't any reason the players couldn't start the Group Tool, create their character data there and then save them to a file that they mail to you. The sucky part would be to combine the files all together. You could use the Actions-->Add Group menu option and load each player's file into the encounter one at a time. Once they are in an encounter you can either drag and drop them to a single group as needed.
