Referencing a UDT Element's value for another element of that UDT's OPC tag path

In my PLC I have a list for the last 10 cycles of the machine what the slowest station was in those cycles. The list contains an index of a station description list. Basically I get the number 10 and now I look at the 10th element of a string array in our PLC to see what the station name was.

I am trying to figure out how I could implement this using UDT’s in ignition. I should be able to have an index member and then a seperate station description member that uses the index as a parameter to read a string from the PLC.

However I do not see a way of indirectly referencing like that in an OPC Path in a UDT. What’s the alternative, am I missing something simple here?
