Hi,
That's not available in HikaMarket even if there is some parts in the "loadVendor" function which could allow you to implement a switch (like the currency switcher).
So it is possible to imagine a custom module which would allow your vendors (with several vendor assignation) to perform a switch.
After that, I can add your request in the HikaMarket TODO list but I am not able to provide you any schedule for his implementation.
