Using the digital work simulation package, modify the existing circuit I have made which only supports four bit addition/subtraction to support eight bit binary add/sub.

https://imgur.com/a/Kusw1Z7 - this is a link to a screenshot of what i have made thus far within digital works application. The circuit on the right is currently only able to support two four bit binary values being either added or subtracted with a press of the button at the top. what i want to do is support two signed eight bit binary values instead.

https://we.tl/t-gzkd1oicBy - here is a link to the .dwm file. You can open it within digital works application (which can be found here - https://en.freedownloadmanager.org/Windows-PC/Digital-Works.html ). Any help is massively appreciated.
