Page link in Arrow

[novski]

Hi
Im drawing A/V Systems and have a quesiton to this: http://www.visguy.com/2009/05/25/how-to-count-the-number-of-items-in-a-list/
I have made a Arrow where i point out a Signal that is going to a other page/tab..
Now because i change that so often and have to write the exact name of the page to that Arrow by hand im wondering if its possible to get a dropdown that shows me the existing pages in my drawing and lets me choose it...

any sugestions how to make that?
best regards
novski
