Only toe in is adjustable on the rear (and the front).

Inner edge wear is usually caused by camber of the tire. (and usually won't be fixed by adjusting the toe)

Inner edge may have gotten worn when those tires were on the front due to worn front end parts, and was not noticed at the time

Be careful you can spend a lot of money trying to make your $400 set of tires last 25% longer.

IMHO (having owned a Volvo shop for 38 years) alignments are one of the most oversold service jobs. From the shops point of view it's great everyone has been taught they need them every x period of time, when in reality RARELY do, and it's mostly profit for the shop.
Most shops make more money on the alignment than they do on a set of tires

And if the guy at the alignment place is not interested in working on your car you really should find someone who is. A disinterested service person is not going to give you good service, because he does not want to touch your car to begin with. And you certainly don't want to "quibble" with any sort of service person - (if you want good service) - even the person making your fast food!
