Setting one MarketPress store for all my sites in multisites

Hi again!

Forgot to ask you if it is possible to set just one MarketPress store to populate all of my own additional sites set up with the multisites. I have two additional sites set up by topic. I don't have the time or elp to set up each store in the other sites. I have over 100 products and since the info for the store is the same (except for the URL under each site), I was wondering if there is a way that I can link my main site's store to the other two.

Thank you for your prompt reply,

Kind regards,

Barb
