How to update parameter value at each step in COMSOL solver?

Dear community,
I have a numerical problem I am trying to solve where I have to replace a variable inside my PDEs with an integral value calculated at each time step of the numerical procedure.
So, call my variable parameter x and call the field i am solving for Y.
I need to make sure that at each time step of the relaxation procedure x is replaced by Q/Integral (Y^2) over the domain, where Q is a constant I set. Convergence will then have a solution with an x that respects Q = x * int(Y^2).
Is there a way I can do this in COMSOL?
I apprecieate your help!
Gianni

Gianni,
maybe an integration coupling operator in the respective domain can solve the problem.
