How to latch the value of an array signal at a particular timestep using Simulink

Hi,

How to latch(hold) the value of an array signal of size 200(input), if a required condition is met(condition may be provided using a Switch block) at a particular timestep using Simulink ?

The input needs to be latched at that instant when the condition to latch the value becomes true and it should hold that value throughout.

Note: The array input is uint8 type.

Any feedback is appreciated.
