Display One Value and Store Another in DFF

Summary

Is it possible to display one value and store another in DFF

Content

Hi,

I have created a DFF on the Position Details page. Due to business requirements, I need to display one value to the user, but then store another value.

Business case:

-- The DFF is currently set up as a value list which displays a list of numbers to the user (e.g. 100-1000). Then, there is a second value list which is table-validated from the first value list. If the number in the first value list already exists on a position record, it will appear with an asterisk (e.g. 100*) to warn the user it has already been used (however they may still wish to select it for the position). The second value list is obviously what the user sees in Position Details
