Data manipulation in order to make record type

Hi All ,

In the attached Screenshot, two values are shown for the project ID, and I want the custom field name to repeat itself twice and the custom field id to repeat itself twice as well. 

I've added code snippet to what I've currently written for reference  and 

Output should look like this 

map

project id  list of number(integer)-2 items
   18800 (number(integer))

   12405 (number(integer))

customFieldName  list of (Text)-2 items

   "2nd Outreach" (Text)

   "2nd Outreach" (Text)

customFieldId. List of Number (Integer) -2 items

   28306 (number(integer))

   28306 (number(integer))

a!localVariables(
  local!result: rule!LGH_intCustomFieldsGET(),
  local!rows: if(
    condition: index(local!result, "success", false),
    valueIfTrue: local!result.result.body.values,
    valueIfFalse: {}
  ),
  a!forEach(
    local!rows,
    a!map(
      projectId: index(fv!item, "projectIds", {}),
      name: index(fv!item, "name", {}),
      customFieldId:index(fv!item, "numericId", {})
    )
  )
)
