Prior to me joining my current company, Partner Center was set up with our marketplace listings in three different instances (one for US, one for Canada, and one for UK). I use the same signin for all three instances.

It's causing me issues, because now our aggregate numbers don't appear in Microsoft dashboards internally (mapping issue). 

Can I simply run everything through the US instance and collapse the other two? Are there tax and banking implications? I believe I can run every private offer through the US instance regardless of whether the end customer is in the UK or Canada.

The listing is identical on the backend, we just have three separate listings one for each instance.
