Mapping an ID to an input value

Mapping an ID to an input value

I'm new to Zoho Forms and trying to figure a way to give a unique numerical value to a value selected from an enumerated field (eg from a drop-down list or a radio button or matrix choice etc).

The reason is that I'm using ZAPIER to update our CRM but for certain items, a value cannot be used and it's numerical value ID (set by the CRM) must be used

example 1 
A Zoho drop-down field has values Item A, Item B, Item C
The corresponding CRM values are 123, 651, 283

example 2
A Zoho matrix choice has values
                     
                 Adults       Paeds
Neuro 
Learning

The corresponding CRM values;
Neuro Adults = 4534
Neuro Paeds = 2321
Learning Adults = 8743
Learning Paeds = 5465


Is there a way I can model this?

Thanks
