Can Spouse A shift this income to Spouse B to take advantage of the tax saving?

Any help is appreciated.

First, a disclaimer: I'm not a tax professional and please consider this as FYI only and do your own DD.

The short answer is no. But what you can do in the future is have two separate bank accounts. Spouse A's salary goes into account A and Spouse B's into account B. Spouse A pays for all household expenses from account A and spouse B does the investing. That way, slowly over time, spouse B, who has the lower income gets investment income taxed in his/her hands.
