Usage: Simply enclose the filename prefix with two underscores. For example, use __lingerie__ in the prompt. For instance, "shot of a beautiful 18 year old girl, wearing __lingerie__". This will cause one of the items from the list to be inserted into the prompt.

For example: "shot of a beautiful 18 year old girl, wearing Leather g-string".

The next prompt in the batch might be: "shot of a beautiful 18 year old girl, wearing Triangle cup thong set".
