Simplest way is to use celebrities. You can mix them like "HenryCavillKeanuReeves" "KeanuReevesEmmaWatson" switch races/gender etc. since the model's training data contains lots of celebrities, it would be able to produce consistent images
in "Create Characters" page you can save characters(eg: jack), and later in the Prompt box in "Panel Creator" you can refer the characters with @ mention (eg: @jack looking at a phone) internally the prompt will be updated with the sub prompt for the character
