Is it also possible to use `Revise.track(Random)` but develop `Random` in a separate folder and not `/path/to/my/julia/share/julia/v1.1/Random/`?

I tried @kristoffer.carlsson’s suggestion in [Editing a package in stdlib - #5 by kristoffer.carlsson](https://discourse.julialang.org/t/editing-a-package-in-stdlib/10199/5) but couldn’t get it to work. The `pushfirst!` doesn’t seem to have any effect.
