Extending Standard account Fact Sheet with Custom BO fields

I have created one custom BO with 2 free text fields. The fields are embedded in the standard account screen in a new tab.

The custom fields have to be available in the account summary fact sheet as well.

BO Definition:

[AlternativeKey] element AccountID: apCommonGDT:BusinessPartnerInternalID;

node Note1[1,1]

{

  element ID:ID;

  [DependentObject(TextCollection)] node FIELD1;

}

node Note2[1,1]

{

  element ID:ID;

  [DependentObject(TextCollection)] node FIELD2;

}

Is it possible to extend the standard fact sheet with these custom BO fields ?
