How to add more values on the seeking for section

In the section ‘seeking’or ‘looking for’ there are only three options: male, female, couple. How do i add more values say trans for example. Also is there a way i could link the values to display the one from one of the taxonomies i have set.
Example: I have created a taxonomy about ‘profession’ which displays doctor, engineer, athlete etc. Is there a way to the change section ‘looking for’ to display these values instead of male, female, couple…
