Forced router input?

I have a user route which has routes like get, delete, create etc. Some of the routes I require extra data but in all of them, my input contains:

id: z.string()

id: z.string()

id: z.string()

id: z.string()

I also call this code in all my routes:

const user = await db.query.users.findFirst({
        where: eq(users.id, input.id),
      })

const user = await db.query.users.findFirst({
        where: eq(users.id, input.id),
      })

const user = await db.query.users.findFirst({
        where: eq(users.id, input.id),
      })

const user = await db.query.users.findFirst({
        where: eq(users.id, input.id),
      })

Is there a way to create a wrapper or middleware that implements route logic like

.input()

.input()

.input()

.input() but allows for other routes?
