Overall stock levels?

Hi guys,
First can I say what a brilliant plugin you have here, really is the best plugin I’ve used to implement a shop into wordpress.

I have a small query which I’m hoping you can help me with.

The wordpress I am running is for an events company, basically we sell tables at venues and we use eShop to sell our tables.

Now I use a lot of “options” to describe different companies that can book tables.

My problem is I can’t seem to find a way to control the overall stock of a post, I can only control the stock of the options.

Let me try and give an example.

At the moment I use around 50 options per post, all with a stock count of 1, so only one type of the same business can book per event.

Now just because I have 50 options, doesn’t mean I have 50 tables.
So I need an overall stock control for each item (each ITEM not option)

So I could have 50 options in one item, but say, once 10 options sell, it would stop people purchasing any more even if there are still OPTIONS that have stock if that makes sense?

I’m really sorry if this is a really confusing post, I’ve tried to put it across as best as I can.

Thank you very much,
Eagerly awaiting your response.
