Allocation of all expense accounts except one

Summary:

We have a request to allocate the sum of all expense accounts except for one. How do we create this allocation excluding only one account?

Content (required):

The account range is 50000-79999, exclude 65005 from one cost center to multiple BU/cost center locations and different ledgers based on a %, using the formula function within allocations. How do we create this allocation, even in multiple steps, to create a pool of accounts excluding one, then allocating that amount out to various locations?
