Response Spectrum Analysis on Large Model (STAAD)

I'm running a response spectrum analysis on a fairly large model (11,000 nodes) in STAAD (SELECT Series 6 v20.07.11.50) and combining the modal results using the CQC method. Due to the size of the model there are numerous modes, most of which are not significant. Is there a way to set a modal response significance factor so that when the modal responses are combing using the CQC method only significant modes will be combined and the rest ignored? Thanks
