Interact with target only on slave

I'm attempting to assign a hotkey that will have only the non current window interact with target.
First i simply mapped a key to assist me, then send the in game IWT key (R), but this requires two presses. The first press assist me, but does not interact, then the second press interacts.
I then tried having them assist me and sending various interact with target actions. the ones that work have both characters interact with the target instead of just the slave. When I try setting the window to all w/out current, ISBoxer tells me to not change the target, and it does not work.
I play with click to move on, so i'm trying to have it also not disable click to move when it's done.

Here is a pastebin of my config file

I don't fully understand the various preset interact with target actions so I'm struggling to apply this customization.

Any help would be greatly appreciated!

You can set the Mapped Key to execute on "pressed or released."

It's because the proper Targets are set in the actual Mapped Key that's being used, which, according to the "Virtual Mapped Keys" tab of your Character Set, is going to be the "IWT Standard" Mapped Key in the "Party" Key Map. So, you can go into that Mapped Key and change the Targets of the Actions there.

Execute on pressed or released is working great for me, thank you!
