find -mmin

When trying to use find, there is no -mmin option to allow for minute based selection although there is the -mtime which allows for the day variant. 

busybox.net shows that the -mmin option is available. Is there a way to request the -mmin option be enabled in a future build? 

I am currently using DD-WRT v3.0-r30925M kongat which has BusyBox v1.24.2. 

Cheers,
Bob
