Reassigning SSB Beam to a UE During System-Level Simulation for 5G

I am doing a simulation similar to the "NR Cell Performance Evaluation with Beam Management" example shown in:

https://www.mathworks.com/help/5g/ug/nr-cell-performance-evaluation-with-beam-management.html

Here, an SSB beam is assigned to each UE as the hNRUE object is created.

The flow of the beam information of a UE is as such:

computeSSBToUE -> simParameters.SSBIndex -> ueParam.SSBIdx -> hNRUE(ueParam,ueIdx)

-> hNRUEPhy(ueParam,ueIdx)

I need to control the beams assigned to the UEs in run-time. Is there a way to change the assigned beam index while the simulation is running? Either by tuning the UEs or the physical layer? Could this be done with "release(.)"?

The part of the example code that creates the UEs:

% Create the set of UE nodes

UEs = cell(simParameters.NumUEs,1);

ueParam = simParameters;

for ueIdx=1:simParameters.NumUEs

% Position of the UE

ueParam.Position = simParameters.UEPosition(ueIdx,:);

ueParam.UERxAnts = simParameters.UERxAnts(ueIdx);

if enableBeamforming

ueParam.SSBIdx = simParameters.SSBIndex(ueIdx);

end

% Assuming same CSI report configuration for all UEs

ueParam.CSIReportConfig = simParameters.CSIReportConfig{1};

ueParam.ChannelModel = channelModelDL{ueIdx};

UEs{ueIdx} = hNRUE(ueParam,ueIdx);

% Create the PHY instance

UEs{ueIdx}.PhyEntity = hNRUEPhy(ueParam,ueIdx);

% Configure the PHY

configurePhy(UEs{ueIdx}, ueParam);

% Set up the interface to PHY

setPhyInterface(UEs{ueIdx});

% Set up logical channel at gNB for the UE

configureLogicalChannel(gNB,ueIdx,rlcChannelConfigStruct);

% Set up logical channel at UE

configureLogicalChannel(UEs{ueIdx},ueIdx,rlcChannelConfigStruct);

% Set up application traffic

% Create an object for on-off network traffic pattern for the specified

% UE and add it to the gNB. This object generates the downlink data

% traffic on the gNB for the UE

dlApp = networkTrafficOnOff('GeneratePacket',true, ...

'OnTime',simParameters.NumFramesSim*10e-3,'OffTime',0, ...

'DataRate',dlAppDataRate(ueIdx));

addApplication(gNB,ueIdx,simParameters.LCHConfig.LCID,dlApp);

end
