How can I fit a function to my data that consists of polynoms and gaussian?

I have data that is pretty well explained by a gaussian fit. But some of the data can not be explained that way. So I want to extend the fit with a polynom. But I don't know how to do it with the curve fitting app or the statistics toolbox. Is there another possibility?

but that only fits a polynom to my data. I want to combine gauss and polynoms. Something like that:
p(x)=p1x^n+p2x^n−1+...+pnx+pn+1+a1*exp(-((x-b1)/c1)^2) + a2*exp(-((x-b2)/c2)^2)
