Hi, Im using the 5e roll20 sheets I want to change a halfling rogue at level 5 to a swashbuckler from thief. (wasnt available on creation/didn't know about it) I know the charactermancer can do it but only if rolled back to level 1 and then stuff goes missing. Just want to know where the settings are that will ensure that future changes using the charactermancer  give swashbuckler upgrades and not thief. Ta
