I'm currently trying to set up a tiered pricing model for a rentable product, the "FlexTent Q3", which comes in four size variants: "S1, S2, S3, S4". Each of these variants has its own distinct pricing under the "Time-based pricing" tab in the product options field.

For instance, the "S1" variant of "FlexTent Q3" has an initial price of $13,500, with an additional $1,350 charge for every extra day it's rented. This pricing strategy applies to all other variants as well; for example, the "S2" variant has an initial cost of $18,900, with a daily additional fee of $1,890. Essentially, the pricing structure consists of a base cost specific to each variant and a 10% daily rate calculated from that initial price. However, we're having trouble setting up a system where each product has a distinct initial price and a separate rate for every additional day, as only one price can be set.

One potential workaround I've considered involves using the "reserve" field. The additional "hour/day" cost (represented as the Fine by hour/day overdue) could be the daily price. However, this approach is limited as it can only be set at a specific value. Even if I set a variant price at $13,500, I cannot configure the hourly rate to be 10% of that variant's cost. Instead, I must assign a fixed rate, which doesn't cater to each variant's pricing. The only alternative I can see would be to create separate products for each variant and assign the "reserve" price to that specific variant (now a product)...

Does anyone have experience with a similar pricing model or have found any workarounds for this? Any advice would be greatly appreciated.
