@Jeff Schulz Thanks for posting your query on Microsoft Q&A.

Currently there isn't a way to update the CORS rules via JSON view on Azure portal.
But you can use Azure CLI or Azure PowerShell to update the CORS rules, if you do not want to go the REST API way. For example, to update CORS rules using Azure PowerShell,

Set Storage context

$ctx1=New-AzStorageContext -StorageAccountName "sname" -StorageAccountKey "abc"

Get Storage CORS rule

$CorsRules = Get-AzStorageCORSRule -ServiceType Blob -Context $ctx1      

View existing CORS rules if any.

Write-Output $CorsRules 

Output:

AllowedOrigins  : {127.0.0.1}
AllowedHeaders  : {*}
ExposedHeaders  : {}
AllowedMethods  : {Get}
MaxAgeInSeconds : 0

Update CORS rule:

$CorsRules[0].AllowedMethods = @("Get", "Connect", "Merge")        
Set-AzStorageCORSRule -ServiceType Blob -CorsRules $CorsRules -Context $ctx1
$CorsRules = Get-AzStorageCORSRule -ServiceType Blob -Context $ctx1                                                                                   Write-Output $CorsRules  

Output:

AllowedOrigins  : {127.0.0.1}
AllowedHeaders  : {*}
ExposedHeaders  : {}
AllowedMethods  : {Get, Connect, Merge}
MaxAgeInSeconds : 0

This way, you can update the CORS rules.
