Change separating delimiter in blog post to comma

Hi all,

I'm laying out a client site and am using the blog as a Portfolio.  On the top right of each blog page, I'm using the categories as a way to display the location of the projects listed inside this portfolio. 

The problem I'm having is that, on the root blog page, the separating delimiter is a comma, which is great.  For example, I am listing the locations as something like, "Bucktown, Chicago", so I have two categories listed here: "Bucktown" and "Chicago" and it displays it perfectly.

In the actual blog page, though, you don't have the option of a comma as a separating delimiter and you can only pick from a bullet, space, etc. So, it's now displaying as "Bucktown • Chicago"

Does anyone know some easy code to have this display the comma as it does on the root blog page instead of a bullet or a space?  

As always, any help would be appreciated.  I've tried to edit other code I've found on the Forum to no avail and am a little frustrated that Squarespace doesn't have this as a natural option.
