Assign Port name "Data Type" from Command Window

Hello, I am hoping to get some help with writing a script to expedite some manual bus port setting changes I have to make occasionally in Simulink. Is it possible to change a Bus's Data Type from the Command Window? If so, where would I find this command (or better yet, what is the command I would use)?
I've attached a screenshot to show what I mean. Thanks in advance!

Try it on one block, get and set the data type
get_param('ModelName/InportName','OutDataTypeStr')
set_param('ModelName/InportName','OutDataTypeStr', 'Bus: xxxx')

Using Goto/From block should be no reason/jusitificaiton for doing this. In principle, a signal or bus should be defined only once, preferably at its true source (e.g. a Bus Creator block). All other places like Ports they should be inherited. Once the model is updated, you will see the propagated bus name/definition. Inport block at the root level is regarded as source.
Defining the same bus in multiple places could cause inefficiency in code generation, even when the definition is consistent. When you need to make a change, you have to make the same change in multiple places. When the definition is not consistent, you got errors.
