I think you can follow the logic in the ts-sdk https://github.com/aptos-labs/aptos-ts-sdk/blob/db88e984528a545a240bad876d9ea832fd0c8348/src/internal/account.ts#L809

and in this function you set signWithFeePayer to true https://github.com/aptos-labs/aptos-ts-sdk/blob/db88e984528a545a240bad876d9ea832fd0c8348/src/internal/account.ts#L910

then have the feepayer sign after user signs
