Adding a new side CMS item box (job location)

Hi all,

I am working on a paid job template. As a part of the package, it has a “Job Category” tool which allows a user to see jobs from different departments. This box sits as a side box.

I want to install another side box “Job Location” displaying where the job is (remote, USA, Sydney etc). If there can be a tally against it, that would be great. So something like this in a box:
LA, USA (7)
NY, USA (3)
Sydney, Australia (5)

When you click any of the above, it shows all jobs in that location.

Currently, Job Location is a CMS item, so it should be possible to do. I was thinking of duplicating the Job Category and changing the CMS item to Job Location. But worried if I may break something.

Any ideas? Screenshots or video would be great.

Thank you so much!

An update:

Just noticed in the template that JOB LOCATION isn’t a CMS Collection item although its a field in a new Job setup. Please see screenshot.

So, i suppose in order to get what I want, I will need to customize the template to remove JOB LOCATION as a field and then implement it as a CMS collection? If so, it’s hard & complicated work right?
