cross sentence coreference resolution

Hi,

Thank you for developing this extension.
I wonder do current implementation has an option for cross sentence coreference resolution?
My workaround is adding `, ,` as sentence separator. It seems works well for many cases, but sometimes ingest the separator, so I can not map back.

For example:
**sents:** Neil Mallon Pierce Bush (born January 22, 1955) is an American businessman and investor, `, ,` He is the fourth of six children of former President George H, W, Bush and Barbara Bush (née Pierce), `, ,` His five siblings are George W, Bush, the 43rd President of the United States; Jeb Bush, a former governor of Florida; Robin Bush, died of leukemia at the age of three; Marvin; and Dorothy, `, ,` Neil Bush is currently a businessman based in Texas,
**numbe of sents before coreference resolution: 4**

**resolved_sents:** Neil Mallon Pierce Bush (born January 22, 1955) is an American businessman and investor, `, ,` Neil Mallon Pierce Bush (born January 22, 1955) is the fourth of six children of former President George H, W, Bush and Barbara Bush (née Pierce), `, ,` Neil Mallon Pierce Bush (born January 22, 1955) five siblings are George W, Bush, the 43rd President of the United States; Jeb Bush, a former governor of Florida; Barbara Bush, died of leukemia at the age of three; Marvin; and Dorothy, , Neil Mallon Pierce Bush (born January 22, 1955) Bush is currently a businessman based in Texas,
**number of sents after coreference resolution: 3**

I hope there is an existing solution I did not notice. If not, may I ask for your suggestion to fix my workaround?

Thank you
