This node merges one shared base prompt with up to 5 per-shot prompt additions.
main_prompt: Base prompt that should appear in every output.
prompt1, prompt2, prompt3, prompt4, prompt5: Optional prompt additions for each output slot.
out1, out2, out3, out4, out5: Combined prompts. Each output contains main_prompt plus its matching optional prompt input. If an optional prompt is empty, the output falls back to just the main prompt.
Use this node when you want to keep shared quality or style text in one place while still producing separate prompts for multiple shots or branches.
