adding excel file in add-ins custom toolbar

[excel length]

I want to add my excel file with macro to add-ins custom toolbar.

my excel file (myfile.xlsm) :

- contains many subroutines and events like workbook_open
- contains activeX
- has lots of predefined worksheets.

GOAL/problem:

after converting myfile.xlsm to myfile.xlsa my goal is:
1. when I click myfile.xlsa it will be automatically added to the custom toolbar when I open an excel file
- this I dont know how

2. this add-in SHOULD NOT run yet but available in toolbar when I open an excel file
- myfile contains workbook_open event (I tried to "install" myfile.xlsa to my add-ins but it automatically runs even if I dont need it)

3. when I click this toolbar it will open myfile.xlsm(or myfile.xlsa) as a different workbook and MUST NOT affect the current opened file.

In short basically,my goal is opening the "myfile.xlsm" through add-ins custom toolbar. Instead of opening myfile.xlsm directly I want it to be "hidden" in the add-ins folder.
I hope somebody can give me some codes or files or maybe at least one from the 3 above.

I had this kind of add-ins once (not my file, can't find it anymore), when I opened the file it had been automatically added to my custom toolbar.

I can "install" add-ins manually for some simple macro but with this case,
I've been searching for sometime now yet cannot find a right code for a complicated macro.

i am using excel 2007.

Thanks...
