TPSM843321: Invert Buck-Boost Mode EVM

Tool/software:

Hi TIer

My customer would like use TPSM843321 to do IBB mode DCDC.

Input is +5V , output is -5V current is 0.01A - 0.1A.

Customer want test EVM . I see we only have TPSM843521EVM here.

So should I need modify EVM circuit by hand to get IBB mode?

Do we have some suggestion  how to modify this EVM? Or other easy way?

Thank you very much.
