This is something I do all the time in reports and I use text mode to change the column. I haven't tried to make these types of updates for the Grouping or Filters though. Here is an example for an Issue report where you want to pull the Portfolio name of the resolving project.
Original text mode for Resolve Project:Portfolio ID
valuefield=resolveProject:portfolioID
querysort=resolveProject:portfolioID
valueformat=HTML
displayname=
linkedname=resolveProject
namekey=view.relatedcolumn
namekeyargkey.0=resolveProject
namekeyargkey.1=portfolioID
Updated text mode (changes in bold)
valuefield=resolveProject:portfolio:name <- Removed the "ID"
querysort=resolveProject:portfolio:name <- Removed the "ID"
valueformat=HTML
displayname=
linkedname=resolveProject
namekey=view.relatedcolumn
namekeyargkey.0=resolveProject
namekeyargkey.1=portfolio <- Removed the "ID"
namekeyargkey.2=name
