Subject: Access Nth element in array with CSS Phoebus.

Hello everybody.
 
I've a little question that it seems obvious.
 
I have a PV define as an array that looks like this:

record(aai, "Array_of_elements")
{
    field(DESC, "Test")
    field(FTVL, "INT64")
    field(NELM, "20")
}
 
If I want to access one specific element of that array, for example the 7th, I can just do this:

pvmonitor Array_of_elements.VAL[7]
 
However, in Phoebus' PV Table, I'm trying to do the same, with something like pva://Array_of_elements.VAL[7], but I'm always getting the entire array and not the specific element, how can I solve it?
 
Thanks in advance, Eusebio.
