I think you can do this:
In your StatusData.txt that is in the plugins folder, add these lines.
Copy Image, 66 ,-1// 0
Copy Image (2), 444 ,-1// 0
Copy Image (3), 445 ,-1// 0
Copy Image (4+), 446 ,-1// 0
If it already has those lines for that buff, just make sure the line reads correctly.
This will make it so statustimers won't display status data for this particular buff.
It's been a while since I've done this so if it doesn't work or has issues, let me know.
