Constraints in Global Fit

Hello,
I would like to do a global fit analysis with some parameters constrained but not linked. I have more than 40 waves and would like to enter the same initial constraint for one of the parameters of each wave, but without linking it.
I have not found any other solution than entering it by hand. Is there any easier solution?
Thank you for your help!
You could call the underlying function yourself, see

for an explanation.
