So I am going on my FC to ask more about targeting PCs outside my party. He suggests I use this:

/targetpc

I guess that's the closest thing to selecting a friendly outside my party? Again, I just want to be able to select a friendly during battle mode, especially in fates. If I see a dude in dire need of res or healing, I want to be able to help them. :P Right now, the filters seem to be the only sure bet. Still, I'd like to set up a macro since I don't want to target friendlies all the time. Just in cases where I see they need a heal or res.
