Ability to show Custom date periods in name of report

Suggestion:
I have set up a custom period I call Last Week using From date -7 To date -3
I would like the report title to show those dates in the title when run. They show correctly in the Query tab but would be nice to see them at a glance. Because I am running this report in Transaction Mode I can’t change my headers. I would love to see this in the Title giving the correct dates for {fdate} and {tdate}
Override Report Weekly {fdate] - {tdate}
