Google sheets: Arrayformula with importrange

Question

I'm trying to work with combined arrangeformula and importrange formulas. I want that from spreadsheet1: Table1 P4 value would be taken to spreadsheet2 C3 cell: Table2 and only when i add new link to column "L" it will put automatic value at C4. So i want to use arrangeformula so it will work on whole column, but i want to fix that from all the links i add it would take same "P4" value. Possible?

Answer 1

There is no solution. See link1 and link2

All you can is

={IFERROR(IMPORTRANGE($L3;"Lapas1!A2");"");
IFERROR(IMPORTRANGE($L4;"Lapas1!A2");"");
IFERROR(IMPORTRANGE($L5;"Lapas1!A2");"");
IFERROR(IMPORTRANGE($L6;"Lapas1!A2");"")}

as many times as you wish
