It's a long-standing issue with Wall, and one that's prevented it being taken up by some wikis. Wall itself is a mess of spaghetti and it's allegedly being replaced at some point in the future.

In the meantime, I think your best bet is to email staff in the hope they can get hold of someone to explain if it's possible and how you should go about it. It's possible they might even make a bug report to add the functionality you want. However, devs are extremely hard to get hold of via s:c however, so you may be waiting a while.
