grouping tests to run

I have written scripts across 3 "units" and i need to run them. 



I know how to add test items and then run them but my dilemma comes that i want to only run some tests at a time and other sets at other times. So i want something like 



SmokeTest "abci'

Undo Test "aefghi"

mats group runs "a-i"



Only i will be using test complete, the others will be using testExecute so i am trying to make it easy on them.

 my first attempt i just ended up making 3 files and naming them then having Execute point to the pjs and run. That worked great but i had tons of redundancy between the modules. 



I also tried right clicking on the project in the explorer and adding a new item, but the second item cannot see any of my units in the first one.   I am thinking its something along the lines of //USEUNIT and point to the units in the first project but i am not getting it to play nice with me.  in the end i want it to it to be undo runs:



"Testexecute.exe Collab.pjs UndoUnit /r /e"  



Then at another time SmokeTest runs and so on.

I never want them to all run back to back though, just want to run in random sets but also reuse code to keep down redundancy.
