Overage bucket refill option

It’d be nice to have an option to pay to refill just the overage bucket like $5/$8 for example. (Just like the credit refill before)

So far, after exhausting the overage bucket, the 4-hour bucket feels too small for the rest of the month, and I’m not on the power user level to utilize the $50 subscription. it’d be good if there is an option to just refill the overage bucket to accommodate usage for users where the $8 plan is lacking, but not quite yet for the $50 plan.

There’s just times where users have periodice bursts of tasks but not on a daily burst basis.
