Tidying up the list in Preferences/General/Virtual Machines Folder: drop down

Hi,

Over the years I've moved my VMs around and because of that, I have a few recent locations sitting in the preferences/general/virtual machines folder drop down list.



I've always kept the folder name the same so it's frustrating to click on that drop down and have three folders listed, all exactly the same with no indication of what's current.

It's only a very minor thing but is there any way I can tidy that list up so that it only lists the current location?

Thanks.
