HS Custom Property management is great but quite limiting when it comes to Properties with long lists of options such as drop down for country, industry, or other custom lists.
Using text properties (wich are already searchable) instead of Drop Downs is not a suitable workaround as it sacrificies the quality of data input for long lists' entries which have to be matched to other tools as well (think a company's SaaS product, Salesforce, Analytics tools, etc.)
It would be great to add Drop Downs to be searchable properties well. This would immensely increase customer experience for form entries.
