How to Create global product navigation menu to across all multisites sites

So far I have used product categories to create a menu which can be copied easily to all sites by using the template plugin to duplicate all product categories to each new site then I have been adding these to the wp-menu to create a consistent navigation bar. BUT this creates /store/ links and so solution doesn't work as I need /marketplace/ links. ( see )

So I am desperately looking for a different solution which can be automated or easily repeated across all sites, as I plan on having ALOT of sites/shops and do not want to have to recreate a new custom links based menu for each one if there is an alternative solution. Or is there a way to change the current menu to use /marketplace/ instead of /store/ .
