I have several tabs ..

In each tab, I have square with formula.

I would like to have my first page, a drop-down "SCOOL DOWN" that will take my square (in any tab) so that it appears on my first page, and I can use it in it.

Any formula ?

** So when I will scrolling , makes this square appear in my first page, it is important that the formulas are still in there.

Not sure if you understand..
