Hi! as a matter of fact, yes, "re.Serialized" https://tatooka.itch.io/cbrpnk-reserialized is a supplement that adds rules for longer campaigns.
keep in mind that both this supplement and re.Serialized were designed for the older version of CBR+PNK (https://emanoelmelo.itch.io/cbrpnk) before the original creators made the Augmented edition, with updates to the core rules (I would recommend checking that one first -> https://emanoelmelo.itch.io/cbrpnk-core). Mine are fan-made / non-endorsed third-party supplements.
