USER ROLES extension needed to accommodate more redirects

Good day, I have a website: https://www.paylight.co.za that we use to sell prepaid electricity but only to specific users. What we’ve done is allocate different user roles to a user – of which we have 4 users, so luckily we have been able to use the existing wordpress user role for each person (excluding Admin). Now, if I go onto the plugin on my wordpress dashboard and go under ‘Advanced – Custom Redirects – Redirect per user role, I see the following roles (default wordpress roles) ‘Editor, Author, Administrator, Contributor, Subscriber, Shop Manager, etc.’ and next to each user role is a field where I then enter the URL of the page I want that specific user to redirect to once they have logged in.

Now, the thing is, we need to extend our users from 4 to 12 which leaves me wondering, how do I now do this and only see basically just 2 spaces left to insert user roles that aren’t admin where i can redirect those to…I need to extend to 12 users, then later to a few hundred users…how can I make this possible or have a multi user system where once each user logs in, I can put a redirect to the exact page I only want them to see and NOT the entire shop page? Or if you can’t assist, do you have any thoughts or ideas or referrals for me to go and achieve this. I am very happy with your plugin and have been using it for the past 2 years almost…with no issues…works like a charm…just need it for more users now. many thanks
