Yes you can.
Click on the first tab you want to include in the array hold down th
shift key and then select the tab at the far end of your array of tabs
This should turn all of the tabs white, this means that anything you d
in one of these tabs will change in all the tabs. For example if yo
enter Test into A1 of sheet 1 it will type Test into every tab that i
selected. This can be good if that is your intent if not you can make
mess.
Back to how to change the footer after selecting the tabs that you wan
to apply the footer to you would then go to page set up and change th
footer in the normal way. Once you have added the footer don't forge
to ungroup the tabs you can do this by clicking or double clicking o
one of the tabs when they change color from all white you know tha
they are ungrouped.
