Adding a visual dividing line at the gutter of a two page spread in Publish Online

[Sketchbk]

I am sending a book layout from Indesign to Publish Online. The two-page spreads do not show the a line between pages. Is there a way to add the dividing line at what would be the gutter of the book?

Draw a line on the spine on the mparent page

Thanks- Just came up with a solution myself. I drew a center line with a medium grey color on the master page in the InDesign layout - which is a double spread. I even added a very light grey to white color gradient to look like a shadow in the gutter on either side.

I thought that there might be an automatic fix but this is probably better.

Not an answer to your particular question but this facility of adding column rules can be overlooked and some may find useful.

To add column rules to a selected text frame choose Object>Text Frame Options (CMD-B) and select the Column Rules tab. Select the Insert Column Rules option to turn on column rules and then adjust the following options: Rule Length To extend or shorten the column rule adjust the Start and End values
