Is there an easier way of restoring to the latest backup file via script?

Currently I have to specify FILE= (which backup set) when I write a restore script

USE master

RESTORE database [db] FROM DISK=N'filepath' WITH FILE=1(sometimes can be 2 or 3 ,depending on the latest backup set)

Is there an easier way to get file no without creating an inserting the table as follows?
