Can we tag customer profiles?

Site URL: https://www.thebusinessofefficiency.com

I would love to add tags to customers based on:

1) Products they bought

2) forms they filled out. 
(Example: If they answered a question a certain way like: Are you a new or existing business owner)

3) email lists they signed up for.

Kajabi is really great for this, but I just love squarespace design. I'd love to make the change but need to know if this is a possibility yet.

Thanks all!
