Get only one specification

Hi,

I found out how to tweak the code to get for example the date of the post-jobs by rewriting get_awsm_job_details but now I would like to be able to display only one of the specification.

Currently, looks like your function awsm_job_listing_spec_content get an HTML snippet and print it (doing a loop on every specification).
I’m new to PHP and got some difficulties to figure out how I could get one specification that I would chose (e.g. get only job-category specification). Is there already a function in the plugin?

Thanks in advance for your time and help.
Best regards.
