[Theme:Listify] add (3rd party)plugin in the job submission form

Hi, I’m using listify theme and it provides a job submission form.
However, I would like to edit this submission form such as adding a 3rd party plugin called, “pinpoint booking” plugin I purchased.

I would like to see the follwoing,
when I try to add a job, in the submission field, I would like to see the booking plugin embedded, just like the shortcode working in the post or page, so that the the plugin pops up and asks to configure..

Anybody could help me?
I really appreciate your help..

**I’m not sure if wp-job manager plugin will do it, because it is only doing some text change and adding field and stuff. as far as I searched related documents.
