Related labels - sorting alphabetically

[Vash Soundur]

Hi there, 

I have created a simple page with lots of different files, and I hae used labels to categorise the files, so that they can be found easily. 

I have embedded the page with the "labels list" macro so that the user can see a full alphabetised list of labels. When the user clicks a label they are taken to a new page (not created by me) which displays all pages using that label. On the right-hand side there is a list of labels called "related labels" which is great for doing further filtering. HOWEVER my issue/question is, is there any way of sorting this list alphabetically? Because I have not actually created this page myself, I dont have any editing options. 

Thanks
