Hey there Ed!
There actually is a feature on Wiki Tree that does that. At the top of profiles (just to the right of the person's name) in your tree is an icon that looks like this: -><- . If you hover your mouse over it, it should say "Find Relationship". Clicking on this will open a page that tells you how you are related and lists the family members that connect you. Very cool, right?
All of the icons next to the profile name do something really neat. You can generate a family group sheet, ahnentafel table, pedigree chart, list of descendents, etc. They are very powerful features, and really helpful.
Is that what you were looking for ?
