[feature request] Can the software add automatic ratio calculation and include proportional sorting functionality?

[utopeadia]

By calculating the ratio, you can obtain value for money. For example, all mobile data SIM cards cost $10 per month or $100 annually. However, Card A might offer 100GB of data monthly while Card B offers 50GB of data monthly. If you divide the monthly data by the average monthly price, you can obtain a value-for-money ratio to evaluate similar projects. This allows us to sort subscription projects based on their value for money and decide whether to keep the top N percent of them.

From the settings interface, the software can add a settlement situation under payment frequency, providing a numeric input box (without specifying units to accommodate different settlement items, which could be data usage, storage capacity, or even the number of software features; in other words, the unit does not matter as long as it is consistent for similar items) and two settlement frequency options. (In simple terms, this means slightly modifying the current cost and payment frequency fields into a single line.)
