Subsystem with similar functionality as of "Unit Delay"

I want to replace all the 'UnitDelay ' blocks in a model with a subsystem which would have the functionality of 'UnitDelay' block.
I want such a subsystem because the initial condition to the 'Unit Delay' block should be passed from a custom block(for example a constant block or From workspace block) as the initial conditions are changed frequently. I have the initial conditions stored in an array. Any help is appreciated. I am using MATLAB 2020a.
(Also I can not use the old Unit Delay with IC block because of my requirement limitations)

"I change the value of IC from 5 to 6 and observe some change."
Are you changing the value of the IC from 5 to 6 while the simulation is running, or after the simulation with IC=5 is complete and you want to use IC = 6 for the next simulation?

Does the Delay block meet the need? It can accept an IC from an external source and is externally resettable.

I still don't understand why the Delay block (doc page link in he original Answer) doesn't fit the need. It can support a delay of 1, i.e., a unit delay and also supports an externally supplied initial condition.
