Currently, CloseBot only allows global rebilling settings for usage (e.g., setting $0.02 per message for all clients). However, this makes it difficult to manage high-usage clients where I may want to offer discounted rates. Feature Request: Please add the ability to set custom usage pricing on a per-client (Source) basis, so we can adjust the rebilling rate (e.g., per message cost, seats) for individual sub-accounts without affecting our global agency pricing settings. Use Case Example: I charge $0.02 per message by default, but I have a high-usage client where I want to reduce that to $0.01. Right now, the only way to do that is to lower the rate for all clients, which impacts revenue from lower-usage accounts.
