What do you mean by 'not involved'?

If you select, say, 12 cells (3 rows and 4 cols) and paste it on D1 then
cells in the range D1:G3 will be overwritten with the source cells...

Also if formulae are involved then you may see unintended (by you) impact...

not involved with the copy and paste action are lost. Any ideas?
