You can change TCP also only for one operation and not all of them.
Just select the operation you want to change and run the "Shift location by TCP offset"!
In PS13.1 OLP Tools are automatically available and you do not run the special setup for it.
You can find it under Robot -> OLP -> Shift location by TCP offset.
In addition use Ctrl+F to active the search and enter some text. This will show you the command as well and you can rum from there.
Hmm it works per operation when I use it. Even per point if you so desire.
