I am making a website for a bespoke shirt company and I am trying to do something that I don't know if it's possible:
I have a data collection with a list of all my clients by their email and their measurements. Not every client is a member on my website.
Is it possible that, when someone signs up as a member on my website, it checks whether it is or not that person is a client, and automatically syncs their account info (#owner) with my measurements data collection? This way I can have a better view of all of my clients' data without duplicates...
In other words, if a person is already a client and I have his email, if this person signs up with the same email, I want his measurements to immediately appear under his account.
Thank you very much
