Hancock and Moore Button Tufting

Hello all...newbie poster with a question...

It seems like some of the more popular current H&M pieces have button tufting...like the Sundance and the Lacross sofas/chairs. Wondering if it were possible to add this as an option to other pieces like the Austin High Back Tilt Chair - to sort of make it into a Sundance/Austin High Back Tilt if you could add the button tufts along the leather seams. It would have a different visual appeal from the back and side.
Thanks to Duane and all the posters of this forum...have learned lots by reading thru...

It would be quite costly to do that as a one-off. They have to design a geometric layout for a piece and actually change the way its made to accommodate the button. Its not impossible, but you would pay dearly for that modification.
