Adjoint Solver Design Change with multiple observables and different weights?

Hello,
I have a task to do a shape optimization of a 2D rectangular by using the gradient based adjoint solver in ANSYS Fluent.
I have to minimize pressure drop from inlet and outlet and at the same time also maximizing the heat flux.
I do understand how to put both observables and do the target change for each observable.
but my question is, on the design change, and if i go to the result section, i see the weight for both observables is 1. Is there a way to change the weight for each observables? if yes, how is it? because i cannot find any tutorial about this online.
thank you so much

Hello. I would like to know if the optimization method on fluent adjoint solver can optimize the DPM module (discrete phase model). I don't not find the DPM in the OBSERVABLE. Thank you.
