Hey Simon,
I think what you are looking for is not possible. You the Generator to find the indicators for the Higher time frames, right?
The Generator works only on the current time frame that you have selected, and in this case, this is your lower time frame.
So the best thing you can do is to set the higher time frames as filters, and then run the generator to find some more rules.
You can Lock as well some indicators that you want to have by default.
