Update existing D&D 5th Edition sheets to include TCE content?

I have the module, and when I create a new character all the data (new class variation rules etc) is there. However, character sheets that already exist don't get the new content. Is there a quick and easy way to fix this? The workaround I found would be to duplicate the sheet then start the level 1 charactermancer, dump fill the stats and then adjust it after, but it's a tad on the tedious side.

Can you give a specific example? Some things are set by the Charactermancer Creator, others by Charactermancer Level Up.

So if I create a new Bard, for example, and level it up to level 4 - it gets all the new TCE features. If I have an existing bard, who is already level 3, he doesn't get the new features. If that makes sense?

Yes it does. The standard answer here would be to file a  Help Center Request  (which is probably the best immediate action). But what is really, really needed is a dev-curated feedback thread for the many changes TCE made to character creation that need to be addressed in charactermancer.
