SSAS tabular cube dimension/measure friendly names

Hello,

I'd be grateful for some perspective if anyone has a spare moment.

I've created a tabular model in SSAS/SQL Server 2016. I am connecting to this model via Direct Query. This tabular model has column names like:

SYSTEM_CODE
SYSTEM_VALUE
SYSTEM_REFERENCE
etc...which pull directly from our underlying database tables and views...

I would like to 'translate' these column names into friendly names like:

System Code Number
Current System Value
System Value Reference
Etc... to help users navigate their way around the cube (and to make use of natural language querying, better chart title readability in Power BI).

It there a straightforward way of giving an alias to tabular dimensions/measures without directly renaming the underlying data source structure (like is possible in OLAP cubes) either in Power BI (direct query) or in the tabular cube itself?

Thanks
