Simultaneous nonlinear Regression of two data sets

Hello,

I want to fit two (if it works, I also want to fit threee and four)
mathematical functions to two (in future perhaps three and four) data
sets (gaussian 
profiles); each function has eight parameters to fit, but four of them 
are the same for all functions. 

I first thought of using the Mathematica-Function "NonlinearRegress"; 
but after reading the Online-help I assumed that it only can fit 
one function to one data set.

Is there a functino implemented into Mathematica, which can solve the 
described problem ?


Thanks,
