RAS - Can I remove section suppress condition formula?

I need to modify a report on the fly so that sometimes the 'Suppress (no drill down)' condition formula is completely removed. Optionally I would just modify the formula to return FALSE so that the section appears. It seems like the code below works when the section format 'EnableSuppress' option is TRUE, but does not seem to do anything when there is a suppress formula for the section.

is this possible to do?

Thanks

Helen

private void RemoveSuppress(CrystalDecisions.ReportAppServer.Controllers.ReportSectionController ctlSec

    , CrystalDecisions.ReportAppServer.ReportDefModel.Section sect)

{

    CrystalDecisions.ReportAppServer.ReportDefModel.ISCRSectionFormat

    secFmt.EnableSuppress = false;

    secFmt.ConditionFormulas.RemoveAll(); // *** Should ensure the condition formulas are removed right?

    ctlSec.SetProperty(sect, CrystalDecisions.ReportAppServer.Controllers.CrReportSectionPropertyEnum.crReportSectionPropertyFormat, secFmt);

}

private void doOutput(CrystalDecisions.ReportAppServer.ClientDoc.ReportClientDocument oras)

{

    CrystalDecisions.ReportAppServer.Controllers.ReportSectionController

        sect = oras.ReportDefController.ReportDefinition.FindSectionByName("DetailSection1");

    RemoveSuppress(oras.ReportDefController.ReportSectionController, sect);

    CrystalDecisions.ReportAppServer.CommonObjectModel.ByteArray

        boByteArray = oras.PrintOutputController.Export(RASDefModel.CrReportExportFormatEnum.crReportExportFormatPDF, 1);

    boByteArray.Save(@"c:\temp\r.pdf", true);

}
