Bought DataBridge V2 - trying to figure out the ins and outs of creating own CMS

Hello, I recognize this might require a premium ticket, which I am opened to. I decided to buy Databridge V2 in the hopes of creating my own CMS's for clients. I was able to create the DataAssist CMS and security pages from the wizards...but not too sure where to go from there?

Do I design my own actual pages for the CMS and then use a php include file for the WebAssist generated pages? If not, do I just put my design over the generated pages?

Is there a simple way to add a "history" feature like PowerCMS has?

Is there a simple way to create a template page like PowerCMS has (so a client can add in their own pages)?

Is there a way to add custom classes to the toolbar that a client can select from (ones we used in the design)?

Is there a way, once I get my demo CMS together to basically copy it to my other client sites so I don't have to go through the process for each site? (I realize I would have to connect their unique pages to it, though I was hoping to somehow set up a "Master" version that I could easily deploy.

Thanks for any help you can give - I have been an exclusive PowerCMS user over the years, but hoping to learn creating a custom CMS through PowerCMS for more customization/etc. I am not super well versed in the ins and out of MySQLi/PHP but trying to learn! The video tutorials for Databridge seem to be for v1 and not the new wizard's pages.
