Is it possible for each seller to create their own product attributes, and for these attributes to be used only by him? if I'm not mistaken, on Nopcommerce the attributes must be created by the administrator, and then they can be used by all the sellers ... if instead, through the ACL, I enable the permissions on the creation and modification of the attributes, when he modifies for example 'colors' in 'colorA', this change affects all seller users and the admin, so it's not okay .... so in summary, my question was this: each seller must be independent to create their own attributes, which must be associated only with him ... is it possible through a plugin, or is it necessary to modify the Nopcommerce code?
