wrap: hide sub-titles?

[#1]

In GRaph Builder, "wrap" is a nice option to split a data set into small pieces and generate many sub-plots.
But sometimes, the window is just filles with the "titles" of the sub-plots an there is no space left for the plots.

Is there an option to hide the titles of the subplots?
In the "wrap" context menu, there is an option to remove the "title" (here: "data"), but not the sub-titles.
And in the red-triangle menu there are options for the X and Y axis, but not for "wrap".
