Adding Conditions To Contact DB Field - Backend CRM DB

The Wix instruction is great, can anyone advise if they know where we can add extra features to help Wix along, I not the fields conditions in the contacts DB are all “and” conditions, an “or” option would be great.

Also adding new condition options to the filter fields would be a great addition.

Has anyone identified where we can embed new conditions so they remain resident in the backend CRM
