Select Characteristic from product listing page

Hi

I hope you can assist, we use Hikashop to sell online courses.
To enroll the individuals into the correct groups within the course in Moodle we use Joomdle's plugin that links a specific characteristic to a user group in the course. (Just some background)

For a specific course I would for instance have two characteristics, for example (CPD and Extra Exam)

I would like to use the product listing page to display the courses.
Option 1: On the product listing page only display the first variant (CPD in this example) once a person has registered for that variant Hikashop adds them to a usergroup " Course 1 - CPD", if the person then goes back to the product listing page it should no longer display the first variant but must now display the second variant (Extra Exam in this example) (This would be first price, basically I want to set it up that Variant 2 is depend on variant 1 being purchased previously)

Option 2: Instead of displaying the "Choose options" button allow the person to select the option from the product listing page and click add to cart.

Hi Nicolas

Thank you for the prompt response like always.

1. I have managed to get it so that Characteristic 1 displays only and then once they have been added to the group characteristic 2 displays, is there a way to set it so that Characteristic 1 only displays if not in group 1, so that only one characteristic displays at any given time.

2. could work as an option for allowing selection of the characteristic.

I have creates a product view for this popup which basically has everything stripper away with only the Price, Characteristic and Add to cart button that remains.

Is it at all possible to copy the code from this view, into the "Image Title" view override so that it displays the characteristic selector, characteristic price and characteristic add to cart button in the "Image Title"

1. Basically what I am trying to find out is. Hikashop is capable of displaying a characteristic based on user group, is it also capable of hiding a characteristic based on user group.
If I have two characteristics is it possible to set it up as follows
Characteristic 1 = Display on user NOT in group 1
Characteristic 2 = Display on user in group 1 but NOT in group 2

2. That is unfortunate.
Is there absolutely no way to pull the info from the product page view into the listing view.
If Hikashop is capable of displaying the "Characteristic available values" on the listing page is there no way to modify this code to display the actual characteristic selector.
