Update a fixed dimension vector Simulink

Hi! I'm using Simulink and I'm counting the cycles and I have to rearrage them base on the torque level. So, I have to update a vector 125x1 (one for each class) and put inside the cumulative number of cycles performed in the corresponding class. How can I do it? Thank you!

A block that may be helpful for this could be the 'Assignment' block:

This would allow you to assign values to specific elements of the signal.

I already considered this option, but the 'Assignment' block just repleace the old value with the new one, while I need to increment it step by step. Any other suggestion?
