Combining the SRM responses for two internal standard compounds to produce a single 'internal standard' used for quantitation purposes with MassHunter Quant software

Hi Everyone,

Is it possible with MassHunter quantitation software to combine the SRM peak responses for two internal standard compounds, for example with PFAS analysis, 13C2-PFDoDA and 13C2-PFTDA, and use the resulting combined response as an internal standard called ‘13C2-PFDoDA (C12) + 13C2-PFTDA (C14)’ for PFTrDA (C13) quantitation?

If it is possible, how is it done?
