Forms Design on how to include a series of Metadata members of CC dimension

Summary:

The Cost Center hierarchy has nearly 54k members and to display the centers in the form wherever there's Trial Balance data for expense accounts is not rendering the form and gives beyond Threshold error. So in order to restrict the Cost centers on the form, is there a way to display only the Cost centers starting with (say for e.g.) XU*, XB*, etch (i.e. starts with specific characters) in the form layout?

Any leads would help!
