Websites and setting up different cookie consents for each site

Hi 

We have 4 website that I need to set up different cookie banners for each site as they all carry different cookies. for example

- https://mywebsite.com/

- https://mywebsite.com/example1/

- https://mywebsite.com/example2/

- https://mywebsite.com/example3/

These are 4 different websites to be clear - I have set up  https://mywebsite.com/ with its cookie banner but need to set up the other three independently as I do need users to go onto each of the sites and see the banner new on each of them even if they have consented with one of the others.  How do I do this? I do not mind having to buy 4 subscriptions. 

Thanks for your help.
