Get list value to use in formfield

I have a list of values stored in my variables.

Using ${mylist} I can see it. But is it possible to get a specific value to use inside my form?
For example I want it to be used in the Name of a form:
Thanks ${mylist[0][1]} -------> Thanks John

Also tried ${mylist}[0][1]
Also tried ${mylist}.get(0)

Not the most ideal, but ${mylist.get(0).get(1)} seems to be working.
