[TYPO3] Share element for several pages

[Rocky]

Hey Group,

Right now I have an element with access property assigned to "Hide At 
Log In". I have following pages will share this element.

Page 1
Page 2
Page 3
Page 4
other page 1 do not share the element
other page 2 do not share the element
....

Is there a way I could just create the element once and make page 1-4 
share the element instead of creating it four time on each individual 
page? I'm thinking of using typoscript in an extension template. But the 
problem with this solution is that my editor could not make any edit to 
it unless I teach he typoscript which is very difficult.

I would really appreciated it if any of you could give me some hints?

Thanks a lot in advance!

Rocky
