Sliding/Fluctuating Price

Hello! I just spoke with Amanda from your team, she’s awesome! She told me to come here and suggest a new feature.
Often, my clients give me the freedom to choose the number of photos I take, allowing me to select the package I believe best fits the house. I would like to create a service labeled "Photographer's Choice" with a price range of $100 to $275. This way, when clients choose this package, they will understand that the cost could range from $100 to $275, depending on the number of photos I take. I am unable to determine the exact number of photos before the shoot, as this decision is made after shooting and editing. Therefore, I cannot offer a package with a fixed fee. Additionally, my pricing is not based on square footage or time spent, so those options are not applicable.
Hopefully you consider! :)
