Focus targeting

All,

I'm have a mod idea that I'm playing around with and have run into a roadblock.

Is it possible to have access to a party or raid member's focus target? For example, if I wanted the name of the second party member I could use:
Code:

UnitName("party2");

or if I wanted to get the name of the target of the second party member I could use:
Code:

UnitName("party2target");

and so on.....Is there such a thing as "party2focus" or something like that.

A little more detail on what I'm doing....I have some secure frames that I want to be able to target a party members focus (these will be set before combat). Is there some way to do this?

Thanks.
