Creating top level in already existing filter conditions

[ÁlvaroAl]

Hi!

First of all I apologize if I am not asking in the right way or in the right place.
I am a beginner Campaign user and when setting the filter conditions we had a question/problem.
In my company, filter conditions tend to be complex and changing at the same time. It has already happened to us that in some filter conditions it has been necessary to add an "or" to the total of the already existing syntax. To be able to do this, it is necessary to be able to lower the entire syntax one level or, in other words, create a level higher than the syntax in which to do the "or".
Does anyone know how this can be done without having to delete everything and recreate the filter conditions with that new "or"?
I am attaching an explanatory image with an example of what I have now and what I would need to do.
We would greatly appreciate any help on this.
Thank you so much.
