Hi,
There is no option to do that.
Like I wrote in my previous message, HikaShop can override the "contact" emails to send them to the vendors or, not override and let HikaShop send all emails to the store administrator.
If you want to change how the system works, you would need to modify an HikaMarket core file or to create a custom plugin to do that specific task (and deactivate the HikaMarket feature).

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