Jetpack Carousel two gallery linking

Dear Jetpack Team,

I am spent a lot of time for searching way how would be possible to link several galleries and didn’t find solution. Currently I have two galleries, which are separate with “<!–nextpage–>” code. My question would be, how can I link two galleries, that photos from two galleries would be shown with Carousel method? My page http://www.gfoto.lt/vestuves/
Waiting answer.

Regards,
Andrius
