SSH Proxy pass text instead of use file

[kevincrick]

With SSH proxy you provide the path to your file and then this will be used when connecting to the device.
Can we pass text which would be the contents of the file instead of the path to the file?

At the moment I have multiple proxy files and dynamically generate the file path based on some criteria from the host.
I use Netbox for inventory and the devices config-context is available when dynamically generating the ssh config file path.
