Configure UPS with two separate Access Keys

I am configuring 4.20
I have a .ca store which ships within Canada and a .com store that ships within USA. I am B2B so cannot ship cross border. From UPS perspective these are domestic shipments and required that I set up two accounts. If I want to ship within Canada I use one account, and if I want to ship within the US I use the other account.
The UPS plugin only allows one configuration.
BTW I am also setting up Shipping Director to manage the complexity of the shipping options.
How can I set the plugin up so that the freight rate is queried based on the country and the account?
Thanks,
Rob

Multiple origin addresses can be configured in the core Shipping Settings page by using the "Multi-store configuration for" drop-down.
However, multiple UPS accounts would require customization of the UPS plugin.

Is it possible to install more than one occurrence of the UPS plugin? and change the Friendly name to identify each account?

Installing exact same plugin multiple times is not possible.
You can duplicate the plugin with different names and properties and can use it though. (You may need to change the class library name, namespaces of the classes and values inside plugin.json(systemname, friendlyname and filename ))

I would attack this by going through the UPS plugin source code and duplicating the AccountNumber, AccessKey, and Username/Password properties as necessary, everywhere they occur.  Then you can handle which to use based on StoreId (also handling the origin address as New York suggests), probably in the "GetRatesAsync" method of UPSService.cs

There is a 'standard' way of handling "Multi-store configuration".  See the SendInBlue plugin as an example.

Did you ending up coming up with a solution? Because I am needing the same thing - different ups accounts for different stores in multi-store configuration

I worked with Shipping Director and we got it to work through the programmer that supports/hosts version 4.2 for me.
I did set up two separate UPS accounts. In US the service is "Ground" . In Canada it is "Standard"
If I recall Shipping Director did suggest a modification in the plug in to allow for two separate UPS accounts.
