One method is add a UDF to the main table the report runs off and use a script to mirror the value from the field you want to the UDF. The UDF should then appear in the report selection grid.
The other method which is a bit more hacky is to use a UI post-load event to add the field to the grid but this will only work if the field i part of the primary grid, at least that has been my experience.
I don't have any experience with the time card/track in 2018 so i can't say for sure either of these methods will be feasible.
