Wordpress support for DirectAdmin

Hi there, I'm new to the forum, and I am a web designer who runs a VPS for his clients. I'm not very experienced with command line proceedures, so most of my work is done through the admin control panel.

We run WHMCS and would like to have Wordpress accounts automatically provisioned when clients sign up. I know there is a way to do this via Softaculous, however the process is clunky and hangs up on occasion. I have read where this support was offered by DA in the "Pro Pack" which is now no longer available.

So my two-part question is: Is there a plugin or native process within DA that will allow us to facilitate this? Also, when we are creating user packages, there is an option to choose "Wordpress," however, when I select it, it defaults to un-selected on save (see video below). So what exactly service is this checkbox referencing, and why isn't it working?

Any help would be greatly appreciated!
