I want to do the following:

I have one sheet that mainly has tables with data and tables with totals
from these data etc.
I would like to have something like the "split" function", i.e. half window
shows the data-tables whereas the other half window shows the totals-tables
of the same sheet. The difference with the split function, is that I would
prefer that these "half" windows show only parts of the same sheet, i.e.
half-window shows ONLY the data-tables and the other half-window shows ONLY
the totals-tables.
Is that possible?
