Can this be done in OpenCart - login to product pages?

Firstly I've not been using OpenCart for a while and am still using version 1.5, so please bear this in mind.

I'm looking to create corporate products, where the customer can log into their own exclusive page to re-order items and pay.

I am currently using a WYSIWIG web builder to create this, but with the need for responsive sites nowadays, it becomes a pain in the butt as I have to create multiple instances of the site in different sizes to suit the plethora of mobile device sizes out there.

Obviously the responsive web templates with OpenCart I currently use are a breeze and a much better option, but not sure whether OpenCart can actually do what I require? Am hoping one of you guys that knows the program backwards and are a genius with it can advise. In short I want to give the customer their own exclusive page, where their wholesale prices remain hidden to everyone but themselves. I want them to be able to click and buy from that page of course.

Can OpenCart do what I want? I am guessing the answer might be no, but thought I'd ask the question on here, in case someone has already gone down this route.

All comments, advice and suggestions would be welcome....... Thanks..

Well, basically this can be done.

To be honest, I am using such behaviour already since a few years in 3 of my extensions.
There are only a few lines to add in a few files and you can restrict categories and products to defined customer groups.
Maybe other extensions already exist, but I am too lazy right now to look after.
If not, and you are interested - you can contact me always.

Thanks for your reply.... Good to hear that this is feasible to do in OpenCart..

Guess the next stage is to explore the code and structure and have an explore...
