Automatic verification of Slow Way using two adjacent Slow Ways?

There are certain Slow Ways that could be automatically verified from two adjacent verified Slow Ways.  An example of this is Grewha (verified) and Gresim (verified) could automatically verify Whasim.  Whasim is made up of half of Grewha and half of Gresim.

Whasim has not been reviewed or verified, except it has as half of Grewha and half of Gresim.

Can this be examined as it doesn't make sense to require a route to be reviewed and verified when it effectively already has been?
