JasperReports-subreports using one query

Hello,

I am using JasperReports to generate PDF reports, using one master queryString, and two additional subreports (every subreport generates new query).

I faced performance issue, regarding to number of queries which are executed, it takes too long time to all queries be executed.

Is there any way to use subreports (i need this for isolating common layout) but use master query report data for filling up subreports with data.

I want to avoid somehow generating query for each subreport.
