bsd-simplified license text without disclaimer

We have a bsd text in several debian copyright files tagged `BSD-2-clause` which is just first two clauses of `BSD-3-clause` , so basically with a mention of disclaimer without the disclaimer itself. This isn't getting detected by scancode exactly, so a new rule (or maybe license?) needs to be added but I'm not sure of the license-expression, since it's different from `bsd-new` or `bsd-simplified` or `bsd-no-disclaimer`, more like -> `bsd-simplified-no-disclaimer-text`

Note that the disclaimer is present elsewhere in the file in the `Bsd-3-Clause` License Paragraph.

Should this just be a Rule or a new License? What should the license-expression be ?
