Have you looked at UGameplayEffectExecutionCalculation you can reference it in the CustomCalculationClass and it can take multiple attributes that you can do whatever you like with there’s a good write up here and and excellent implementation example in the source code.

4.5.12 Gameplay Effect Execution Calculation](GitHub - tranek/GASDocumentation: My understanding of Unreal Engine 5's GameplayAbilitySystem plugin with a simple multiplayer sample project.)

Thanks for the answer. But UGameplayEffectExecutionCalculation not called for effects with durations no period, because there is check in source code:

// Should only ever execute effects that are instant application or periodic application
// Effects with no period and that aren't instant application should never be executed
check( (Spec.GetDuration() == UGameplayEffect::INSTANT_APPLICATION || Spec.GetPeriod() != UGameplayEffect::NO_PERIOD) );
