Align group on a specific position

Still lost…
Have created a part and filed as a group.
Now I want to position that group at an exact position.
Example: Have a hexagon shaped floor and want to place a “wall” (with each potentially being a different group; e.g. for windows etc) on each side of the hexagon. Moving the group on all three axis is quite cumbersome.
Would really like to know a more efficient way.
Many thanks
