I’ve never seen that offered, only full licences. A bit late in the game now with 2024 coming out soon, but where would one find the upgrade? If it’s in the marketplace, I have a personal boycott on that due to other anti-consumer practices.
And back to the drill bits, you are still making a bad comparison. The bits are a physical item. If my only choice was to buy the multi-pack, I would have the option to resell the unused bits to recoup some of my cost. Not so with digital media.
