Different Amplitude for Sink temperature & Film Coefficient

Dear All, I need to perform a Heat Transient Thermal Analysis. Correct if I’m wrong but it seems that it is not possible give a different Amplitude for the Sink Temperature and Film Coefficient.

Indeed, amplitude is currently supported only for sink temperature: Amplitude support for film coefficient and emissivity - Feature Requests - PrePoMax

You would have to edit the keywords manually to define it for the film coefficient.
