Theoretically this should be possible, but I have not tested this myself yet. Most of the time CRM uses the description field in Custom_Tables to display the description of a field. That's how the Cases RefId is done. 

So here is my approach

1. Update the Custom_tables "Bord_RecDescriptor" using ## values. Use Cases table as an example. Something        like #Comp_Name#:#Comp_idcust#
2. Then follow this article to rebuild all your indexes - https://help.sagecrm.com/on_premise/en/2020R1/Administration/Content/Troubleshooting/TS_RecreatingQuickFindIndex.htm

Wait for the indexes to completely rebuild, and test. Please do this on a test system first before trying to do it on a production database.
