Can Simulink model a microcontroller randomly missing control inputs?

Is there a simulink block that can take an input and at random intervals hold it 2-3 time ticks before outputting? The "Rate Transition" block does this but in a consistant mannor but I'm interesting in looking at something which has random variation in the timing.

I understand that you want to take an input and at random intervals hold it for 2-3 time ticks before giving output which also involves random variation in the timing. This can be done by using a combination of blocks, you can follow the below steps for the same-

1. The input signal enters the Unit Delay block, which holds it for 2 or 3 time steps.
2. The Random Number block generates a random value between 0 and 1 at each time step.
3. The Switch block uses this random value to determine whether to output the delayed signal or the original input signal.
4. If the random value is less than a certain threshold (e.g., 0.5), the delayed signal is outputted, creating the random hold.
