vba - Excel Multiple XLA AddIns use at the same time -

can 2 excel add ins (named differently containing same code) used @ once? , how select 1 use when running macro on ribbon link example?

i have add in lot of code being used in many excel files, want split production , developer add in (only make changes in developer add in).

but since add in settings global excel files, how select want use dev or prod add in?

i can't rid of production altogether, because regularly need work both.

if mean want easier method switch between 2 addins (dev , production) don't use excel addin manager, open addin want if workbook.
