Dynamic Sidebars

No... column control is best-managed by:

1. edits to tpl_main_page.php (where you can disable left/right columns for specific pages)...

// the following IF statement can be duplicated/modified as needed to set additional flags
  if (in_array($current_page_base,explode(",",'list_pages_to_skip_all_right_sideboxes_on_here,separated_by_commas,and_no_spaces')) ) {
    $flag_disable_right = true;
  } 

EG

// the following IF statement can be duplicated/modified as needed to set additional flags
  if  (in_array($current_page_base,explode(",",'shopping_cart'))  ) {
    $flag_disable_right = true;
  } 

There are comprehensive NOTES in tpl_main_page.php for column display customisation

Tried this one so far, and it works flawlessly! Thank you so much. I'll explore the other options too.
