Currently it is already possible to "Group charges by properties" in the Standard Charge model.

For us it's not important that the costs are grouped by a property, but that the usage details on the invoice are grouped by properties. This will also allow it to work on any charge model.

For example:

- On our side we have billing accounts (customer in Lago) and projects, multiple projects can share one billing account

- When a contract is signed, this contract isn't limited to a single project, we mostly sell graduated pricing plans, so the subscription is shared over multiple projects

- On the invoice it would show a usage for the subscription, but it's not possible to have the usage details split per project

So it would be nice to have a feature like "Group charges by properties", but then named "Group invoice usage details by properties".
