Question about the Interop function

I noticed that some of the older tests cases (e.g., TC-DERIVEKEY-1-20) do not have the "Interop" function at the start and end of the test.

My question is, is it allowed for me to add the Interop operation to these test?

Also is it allowed to add the Interop function to Mandatory profile tests if they don't already have it?   I believe the answer to that one is no but I want to ask first.

I am referring to the mandatory profile tests defined last year (e.g; AKLC-M-1-20).
