问题
On Azure Portal, I am able to setup path-based rules which have some default setting, and a list of sub-rules (UrlPathMap).
Each of those sub-rules has a name, paths, backend pool, and HTTP setting that have to be configured.
As I can see I can update this map easily through Azure Portal. I want to be able to create such sub-rules dynamically from code as part of the application installation. I would prefer to do this directly from .NET (ASP.NET Core 3.1) application, but Azure CLI or Azure Powershell script should be OK for me as well.
At this point, I tried to use Microsoft.Azure.Management.Fluent library, Azure CLI and Azure Powershell but I do not see the direct option to do what is need.
Will be really glad to get some help here.

According to my test, we can use the following PowerShell script to create a sub-rule.
Connect-AzAccount
$groupName=""
$gatewayName=""
$poolNmae=""
$httpName=""
$pathRuleName=""
# get original sub-rule in your path rule
$appgateway=Get-AzApplicationGateway -Name $gatewayName -ResourceGroupName $groupName
$pathmap=Get-AzApplicationGatewayUrlPathMapConfig -ApplicationGateway $appgateway -Name $pathRuleName
$t =$pathmap.PathRules.ToArray()
# add a new sub-rule to the path rule
# 1. get the require backendpool or backendhttp settings
$pool=Get-AzApplicationGatewayBackendAddressPool -Name $poolNmae -ApplicationGateway $appgateway
$http=Get-AzApplicationGatewayBackendHttpSetting -Name $httpName -ApplicationGateway $appgateway
# 2. create the sub-rule
$r=New-AzApplicationGatewayPathRuleConfig -Name "rule01" -Paths "/path" -BackendAddressPool $pool -BackendHttpSettings $http
$t += $r
# 3. update the path rule to add the new sub rule
Set-AzApplicationGatewayUrlPathMapConfig -ApplicationGateway $appgateway -Name $pathmap.Name -PathRules $t -DefaultBackendAddressPool $pool -DefaultBackendHttpSettings $http
# 4. make the update effective
Set-AzApplicationGateway -ApplicationGateway $appgateway
