Feeling forced to upgrade unneeded package

can you just sell credit packages, like per 100credits, I will buy until my monthly credits are back up. feels more than wrong buying an upgrade and then downgrade again, more work and steps for all of us , you can sell the credits as high as you want , but no up and downgrades needen no refunding needed etc , pay for what you need, no plan gymnastics. Simple for users, simple for Base44
