Reduced subscription overage pricing

Not sure if this would be possible, but I have feature request for subscription overage pricing. This would be similar to what portal.neuralwatt.com does. Effectively when you buy a subscription you also get a discounted overage rate in line with subscription pricing.

So for example if I bought the ChatGPT subscription if I could get overage credits at a reduced rate of $1.80/10M instead of the $3 standard price.

I think the main value props for me with Routera are that I can use the credit whenever I want for the month (not metered out), and also I have more security/control over my usage. Adding the additional security of overage if I needed at a fair price would lead to me to probably never use any other service/subscription again.
