We would like to add a custom property to products called "catalog number" and one to line items called "extra info". After I do this, I am then planning migrate our current list of products into hubspot, i.e. write a script (that uses the hubspot API) that uploads our product list from outside hubspot into hubspot, with the aim that our sales people will then start managing our product list via hubspot.
I have a few small questions related to this:
1. Is it possible to add these custom properties via the hubspot UI? (e.g. by going to settings -> properties -> create property). If it's still not possible, when do you expect this to be possible?
2. More importantly, if I create these custom properties (say, via the API if needed), will I be able to see them in UI (when going to settings -> sales -> products & quotes and selecting a product and when creating a quote and editing its list of products)?
3. And a bit of a side question - in the developers documentation, is there a page with the list of default properties for products and line items? I could only find this page: https://developers.hubspot.com/docs-beta/crm/properties, but it only has contacts, companies, deals and tickets.
