Isolate exceptions

Pull the few odd cases out of a group and give them their own bucket, so what stays behind behaves the same way. Unlike a full reslice, you move only the misfits, then write a separate rule for them.

Example

In the budget app, one $1,400 annual insurance charge and a $600 vet bill are swamping "Other." Move those two into an "irregular one-offs" pile. The remaining Other now runs a steady $60 a month, so you can budget it and treat the one-offs as savings goals.
