Ramp block having reset option

I would like to implement in simscape a kind of ramp block having reset option, thus that ramp would start rising from zero every time the reset is triggered. I've tried with resetable subsystem block but is of no helpfull.
Have u got any idea how to solve this?

Here is one way with enabled subsystem, where the subsystem comes up with an offset (so if the ramp number gets too large it might be a problem):

There is no ramp inside the resettable subsystem. it is a simple integration as below:

Hi @Andraz
If you have a good understanding of the fundamental mathematics behind a line graph, then theoretically, you should be able to implement the mathematical formula for a Resettable Ramp in the MATLAB Function block. This way, you can avoid using any specialized blocks that require a more abstract programmatic If–Else logic to comprehend.
t = linspace(0, 10, 1001);
p = 2*(heaviside(t - 2) + heaviside(t - 4) + heaviside(t - 6) + heaviside(t - 8));
y = (t - p)/2;
plot(t, y), grid on, ylim([-0.5, 1.5])
xlabel t, ylabel y(t), title('Resettable Ramp')
