Creating a template then bulk updating it

Hey all!

I have a client who is expanding his real estate empire rapidly and has asked if I would help by creating a new site for each new business that he opens up. I have created a template for him and plan to just duplicate and update the copy/imagery…etc. for each one. However, this client is looking to open up 60-150 new businesses within a year and I’m concerned that simply duplicating a template isn’t a great long-term solution.

What I’m thinking will need to happen is the ability to create a Master template and then have the ability to make any updates/enhancements to that master, and have those updates push to the children.

Would this be a custom thing made outside of webflow? or is there anything like a template host within webflow that I could utilize?
