Carry UDF values between samples and sources and tests

Let's say I add the UDF -Sex- to a Sample Source type and want to use the same UDF for Tests in the clinical data module. For Sample Source X I have entered the data value -Male- in the UDF. I then proceed to creating a test connected to the same Sample Source but find that I need to enter -Male- again for the same Sample Source even though I use the exact same UDF. In this example, it would be great if the UDF could be set to carry its value between entry points. Adding such a setting to UDFs would improve their functionality.
