Ability to search where keywordtest/script is being used in other keywordtests.

as an example I made a few keywordtests that calculated certain dates. now in my project explorer there is no way to know where this test is being used. I try to use test parameters for a lot of things to reuse the tests in other places.  that way i dont rewrite teststeps multiple times

The same for Script functions. if i want to know where this function is being used it would be nice to see where this test/script is referenced.
