Variable of Integration in Simulink

How to integrate a function or any source variable with respect to another variable (" the variable of integration" ) rather than the time counted by simulink when it is run?

i.e. How to integrate this in simulink( how to set the variable of integration to x or using dx rather than dt )?

If the variable x is a function of time x(t), you can use Integration by substitution method

Differentiate the function x using Dervative block multiply with the function and integerate using Integrator block.
