I've found very usefull the possibility to create an action (a Zap) that populate CMS collection out of any Google Spreadsheet row added or cell modified: this is really great (have a try if you never did it).
Now assume you have a Master database in Google Sheet, and that you have a bunch of CMS items uploaded on the site of a customer. After a while the customer, thanks to the webflow editor, can modify on it's own an item or a field BUT there is not at the moment a Zap that modify the Google Sheet, so your Master file is obsolete now.
I've asked Zapier, to add such a functionality: they replied will be happy to implement this if they see there an interest from the Webflow Team or the Webflow Community. This is why I'm trying to get involved more people on this easy task.
