Having users with multiple roles

Hi! I’ve been using this plugin and found it pretty easy to set up and bulk update prices from CSV. On the other hand, my client’s requirements have been increasing and now I need to set up prices in a more complex way. It requires a customer to belong to multiple roles, and whenever the rule matches, a sale price would be shown. It seems that the plugin won’t read any additional user roles on top of the WP core roles, so it’s very hard to achieve what I’m asked for. Any chance this plugin would check for array of multiple user roles instead of just one? Thanks!
