Ability to assign Decorated Products to specific clients

We have quite a few repeat clients, be it brands/clubs etc. It would be really handy if we could create Decorated Products and then have the ability to assign them to specific clients. It would make their ordering process much easier, with all the prices fixed at their rate.

I appreciate that they can log in and reorder items, but for those clients that use the same t-shirt (for example) for lots of their ranges, it's really difficult to know which line is the one they want on that order. With a decorated product, you can name it and give it it's own SKU. You can even put each range for that client in it's own category, making it even more obvious when selecting what they need to order. 

Yes we could do an affiliate site for each, but that would be a lot of work to do for each of our retail clients and over the top when there is a less complicated solution.
