[SOLVED] Customized Sidebars for Different Pages

I tried searching through for this but I don't see it anywhere. If anyone has asked the same question, I would appreciate being linked!

What I basically want to do is create a few of the same sidebar (particularly the left sidebar), but with different content, that I can display on different pages. I know I can already do two different versions (using the inner left and the left), but is there any way I could get five? Then I could select which pages each side bar shows up on.

I would have like Left Sidebar 1, Left Sidebar 2, 3, 4,5... and then pick which pages each one shows up on.

The only thing I found was to edit the functions.php code. Should I go ahead and just do that or are there any other options?

Thank you!
