Install 2 projects same menu item

I have 3 different projects in my visual studio c# that when each is installed on a system they all 3 go under the same: START->ALL PROGRAMS->XXXX_dir XXXX_appl_1 XXXX_appl_2 XXXX_appl_3 I publish each project and have different setup.exe for each project so can I make them all install in the same directory?
