Referral package could match my own

I’ve got a banging promotional monthly deal through one of Smarty’s affiliate and have shared my referral link to my family mainly but sad to see the deal they get is the exact advertised package . I do understand that after two billing cycles Smarty offers a £20 bonus to both myself and my family members but would be great if smarty could offer replica packages on referral rather than widely available standard package deals .. just a small suggestion.🤩
