Check a box that allows sub funds balances to be grouped with main fund balance when running admin fee calculation - instead of creating and admin fee group. So that if the value of the funds together moves the total to a lesser tier. For example, if the main fund has $750,000, and the sub has $300,000 and you assess 1.5% on funds under 1 million, 1% on funds over $1 mill that the calculation combines the funds only to assess the 1%.
