Hi,
We can add that in our TODO list for the payment plugin but we can't provide any schedule for that.
We currently have more than 60 payment methods listed in our TODO list, so the improvement of the "alipay" plugin for the support of the "partner" mode could take some time.
Best regards,

By the way, do not send me private message, use the "contact us" form instead.
