[Plugin: WooCommerce 2.3.13] Product Templates

I am building a site for a retail store in which several people are adding new products all the time. To streamline things for them I created a product template (with all their typical price, terms, and shipping options preset for them) and saved it as a draft. When they’re ready to add a new product they just duplicate that template and edit the details as needed. In theory this sounds OK but in practice I find that I’m having to restore a backup of that template several times a day because someone forgets to duplicate it and ends up editing the original instead. I’ve tried searching for a plugin or some other tool that I could use to create a template that can’t be edited (only duplicated) but so far I’m having no luck. Has anyone else had and solved this problem? Thanks in advance for you help.
