Events and MarketPress integration

Hi

I'm using the Payments via MarketPress Products add-on to take payments in Events+ via MarketPress.

Two questions

- I have to create a MarketPress product to accept payment for an event. Can this product be hidden from all product listings, as it doesn't make much sense when viewed directly, rather than via Events+

- I have MarketPress set to display 'Add to Cart' for single products, which is how I want it for the actual products on my site. For events I'd like the button's actions to be 'Buy now'. Can this be changed just for single events?

Thanks
Pete
