Batch - Add

Hello I'm trying to add await web3.currentProvider.sendAsync in batch.add to sign multiple vouchers but I'm not having success. I didn't find any example using sendAsync is that possible? how I can do that?

Just to provide more context:

Hello, I'm trying to sign two or more vouchers. To sign just one voucher I manage to make it work:

const signedVoucherPromise = new Promise(async (resolve, reject) => {
                    await web3.currentProvider.sendAsync({
                        id: new Date().getTime(),
                        method,
                        params,
                        from,
                    }, function (error, result) {
                        if (error) {
                            console.error(`Error on sendAsync: `, error)
                            reject(error)
                        }
                        resolve(result)
                    })
                })

                const signature = await signedVoucherPromise.then(res => {
                    return res.result
                }).catch(e => {
                    console.error('Error getting signed voucher: ', e)
                    throw new Error(e)
                })

                const signedVoucher = {...voucher, signature}

I tried to add this function to batch.add and didn't work.... I tried to add two blocks of the code above n just one worked .... the other was ignored...... how can I handle it ?
