How to load Image paths using Session Variables into Billboards within Custom Screen

Hello,

I have created a Custom screen with a Billboard control.
In the Billboard properties window, we are given the option to add images to the Billboard.
When adding images, it will only accept images that physically exist from the machine where you have SetupFactory installed.

In my case, I added an image as a Primer File and the image files are then unloaded into the %TempLaunchFolder% location.
And I would like to tell the Billboard controls to load images from this location.

Would it be possible to make use of Session Variables to point to this dynamic location?

Thanks,
