Hi @DaralisP ,
Are you referring to add a page break only when the number of subreport pages is singular? For the page break behavior in the subreport, we usually add a rectangle to set the page break for the rectangle.
I think using custom code about page numbers combined with IIF conditional expressions should do the trick.
I am not good at Custom Code, you could refer to the link: https://social.msdn.microsoft.com/Forums/sqlserver/en-US/4dc33cfa-c9e9-4be6-bf08-166f1a9238bb/ssrs-report-controlling-even-page-numbers-per-group-for-printing-purposes?forum=sqlreportingservices
If I misunderstand what you mean, please feel free to correct me.
Best Regards,
Joy
