Is it possible to create a custom "Pre-fab" quickstart character to select at the beginning of a new game? I know this sounds like "Basically creating a brand new character the most ass-backwards way possible", but the reason I want to do this is so I have the same character to use in the module quests, like "Lost Dungeon of Souls" or "Dusty Dunes", without having to go through the "Create New Character" process every time.

A simple "no" will do.

Well, technically you could make a new level up preset for the game. Not sure if that's what you had in mind, though.

You mean like the "Doctor-Gunfighter" thing? I guess, since there are presets for all the pre-fab characters like "Merwin Tumblebrook" and all.

It might be a little more work than you intend, though. You need to decompress one of the .dat files and add a new level-up scheme to the file that contains them (just a little text editing, but it's tedious.)
