Shower – do about a shower valve stem that is too far recessed after tiling

I am putting a shower back together after tiling it and putting fixtures back in. I bought a Moen universal shower handle trim kit because it was really the only thing I saw in a metal finish with that worked with a push/pull shower valve.

I no longer have access to the valve itself since dry wall, thinset, kerdi, and more thinset is surrounding the valve stem coming out of the wall. Anyway, it is now too far recessed and the handle has a piece (which I forgot to take a picture) that fits over the stem. It is flat on two sides and fits over it and then screwed into it.

Is there an extension piece that one can buy that will connect the two? Any suggestions would be great that doesn't require opening the wall back up. Just something I didn't think of while I was tiling.

The sleeve coming out of the wall can be pushed in further but it won't do any good. The "arms" on the piece that goes in the handle that prevents the handle from being turned passed the top part of the sleeve will just hit the face plate.
