Extend example conditional rule to accept plurals?

Is it currently possible to extend this to accept plurals? E.g., the existence of LAN requires that Local Area Network exist and that's fine, but we'd like to:

a) (ideally) Accept "LANs" and "LAN" and their definitions to cover both the singular and plural. This means that if LAN and LANs both appear in the same file then Vale is not going to trigger on both. Defining one would be enough to cover both.

b) Be able to modify the rule to recognize LAN and LANs and the associated definitions.

Thanks a lot.
