So this is screen is used to create a PATH based caslib, meaning a path on the server. I dont think this is what you are wanting to do.
Potentially there might be a way to use the import function, to pull the xml from your local computer and load it as a caslib. I haven't tried it before but there might be a way to accomplish this. I probably think you would have to use code to do this, and not the UI.
Some good reading:

Excerpt:
"Please be aware of a limitation with data stored in SAS Content. While any file can be written to or uploaded to folders in SAS Content, you can’t access data (ex. .sas7bdat) from SAS Content via libraries (since libraries cannot be assigned to SAS Content folders). Only data that can be read via a fileref (ex. .csv, .txt, .xlsx, etc), can be read from SAS Content (since filerefs can be assigned to files in SAS Content). See working with data in SAS Studio 5 for more information."
So in Studio you might be able to make a filename reference to the fileserver and read it as a base sas data set and then load that dataset to CAS.
This not not the same type of example but shows using a filename reference to save data to SASDrive Content: https://communities.sas.com/t5/SAS-Communities-Library/Making-SAS-programs-stored-on-the-file-system...
