Relate fields in file import

Hello
I want to import the product data, I have the data in a csv flat file
In this case I have a problem with the productSubTypeSelect field, the idea is that the person who fills out the file does not write the subTypeSelect codes, such as 1, 2 or 3, but rather writes data that is more understandable for humans such as: « Finished product » instead of the number 1

I understand that I configure this in an xml file, but I don’t know how to bind

<?xml version="1.0" encoding="UTF-8"?>
<csv-inputs xmlns="http://axelor.com/xml/ns/data-import"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://axelor.com/xml/ns/data-import http://axelor.com/xml/ns/data-import/data-import_6.1.xsd">
  
  <input file="base_product_ejemplo.csv" separator=";" type="com.axelor.apps.base.db.Product"
    search="self.importId = :importId" call="com.axelor.csv.script.ImportProduct:importProduct">   
    
    <bind to="startDate" eval="call:com.axelor.csv.script.ImportDateTime:importDate(startDate)"
      column="startDate"/>
    <bind to="createdOn" eval="call:com.axelor.csv.script.ImportDateTime:importDate(startDate)"
      column="startDate"/>
    <bind to="netMass" eval="1" if="productTypeSelect == 'storable' &amp;&amp; netMass == null"/>
    <bind to="grossMass" eval="1"
      if="productTypeSelect == 'storable' &amp;&amp; grossMass == null"/>
    <bind to="isShippingCostsProduct" column="isShippingCostsProduct"
      eval="isShippingCostsProduct ? isShippingCostsProduct : 'false'"/>
  </input>
  
</csv-inputs>

I have managed to do it with the eval function, but I am asking for 3 values that are fixed, and the idea is for it to be automated and work for any value

    <bind to="productSubTypeSelect" column="productSubTypeSelect_item"

    <bind to="isShippingCostsProduct" column="isShippingCostsProduct"
      eval="isShippingCostsProduct ? isShippingCostsProduct : 'false'"/>
