Need help optimizing Essbase calc script to AGG sparse dimension

Hello,

We have an Essbase database with a large Products hierarchy dimension.  It's a fairly ragged dimension but all the members are just stored and aggregate as + to the next level.  So the nightly default calc script use this syntax to AGG the sparse dimensions:

Set FRMLBOTTOMUP ON;

  AGG ("Products");

Set FRMLBOTTOMUP OFF;

This works fine but we've started to add an alternate hierarchy within the Products dimension.  The AGG also rolls up the alternate hierarchy fine, but I have these "other" members that need to be calculated as a plug for each category.  So I use this code after the first AGG:
