Can we add api calls in required filter in projections?

Hi All,

I am trying to add a custom column using enumeration in standard IFS screen , which is perfectly working fine 

I am trying to enable the field only on certain conditions. Can we add a API call in the required filter?

Trying it the below way but it doesnt work. Let me know if you have any suggestions on this

@Override
entity ResourceAttribute {
   attribute CDays Enumeration(FndWeekDay) {
      multiselect = [true];
      required = ["Res_Attribute_Manager_API.Get_C_Multi_Select_Days(ATTRIBUTE_ID) = 'True'"];

   }
}
