Adding Text To Rank Function

I am trying to rank a list of numbers, such as:

1
3
5
3
4
1

I have no problem with the rank function in terms of the ties showing as duplicate values, however, when this occurs I would like a "T-" to appear before ranks that are tied, and show nothing if they are not tied. Essentially, I want the final result to look like this, without having to manually add the "T-" after the ranking is complete.
1 T-5 3 T-3 5 1 3 T-3 4 2 1 T-5
I have done more complex Excel formulas before, but for some reason this is stumping me.
