LR: editing lens information in Library module

[BillN_33]

anyone know if you can edit the lens information in the Metadata section in the Library Module in LR

I am using a few MF lens - it shows the 24mm Focal length OK and the Exposure, etc. - but the Lens ID is shown as 0.0 mm f0.0 … I would like to amend it to show AIS 24mm f2.8 Nikkor

Can this be done manually - I've tried but get nowhere and google doesn't help

These might help?

Whilst for capture time IIRC you can alter any EXIf information
