Any way to list all objects inside a View, including those in sub-Views

Good afternoon,

Is there a way to list all of the objects inside a View, including the objects that are inside the sub-Views?

I have a View and inside this View I have two other Views.

I want to see is there any way to show (list) all of the documents that are inside all of the other Views within the overarching (main) View.

Is this possible?

Note: what I am trying to achieve is to find a way to list documents in a View that have have different sets of conditions. Since we can't do 'OR' conditions for View filters, I am trying to see if such a method can work.

If someone else came up with another way to achieve this, I would be interested to know.

Thanks!

Patrick.
