Does Jaspersoft support sharing temporary tables between the main report and subreports

I am using Jaspersoft Studio 6.3.1 with Sybase SQL Anywhere 12.  When I create a Sybase temporary table by executing a procedure in a Main report, the Subreport cannot find the table.

This technique does work when I execute the procedure in a Java environment, just before generating an IReport with subreports that select from the temporary table.

Does Jaspersoft support creating temporary tables in a main report, for later use in a subreport?  If so, please refer me to documentation of examples and setup.

Thanks, David
