More granular "require password" options when biometric unlock is enabled

When I enable biometric unlock, I can enable "require password and choose between never, 2 weeks and 30 days.

I find 2 weeks too long and would prefer 15 minutes.

Is there any reason why this is not completely customisable? The setting should have two inputs: A select field to choose between minutes, hours, days, months and never. And a number input.
