Grouping Numbers

I have a table which lists player names, teams played for and the
years they played there and my code looks like this

SELECT AlsoPlayedFor.playerID, AlsoPlayedFor.teamID,
AlsoPlayedFor.TeamName, Min([AlsoPlayedFor].[Year]) & "-" &
Max([AlsoPlayedFor].[Year]) AS [Year]
FROM AlsoPlayedFor
GROUP BY AlsoPlayedFor.playerID, AlsoPlayedFor.teamID,
AlsoPlayedFor.TeamName;

which takes the Min year and the Max Year and displays it like "Year-
Year"

But lets say for example the player played for 5 years so it 1990,
1991, 1992, 1993, 1995

It would display as 1990-1995 but I want it to display as 1990-1993,
1995, is this possiable??? Also I need it to gothe other wayso if the
years are 1990, 1992, 1993, 1994, 1995 I want that to display as 1990,
1992-1995.

PLEASE HELP
