Oracle Seeded Card Expense types vs Business Expense Types (Corporate card transactions)

Summary:

Can someone please help us understand how we can map our Oracle Seeded Card Expense types to our business expense types (corporate card transactions) if our Card Expense types could only be mapped once to one of the expense types?

We have multiple expense types from the client that looks like they share the same Card Expense type.

example:
Expense type = Building Repair Labor
Expense type = Building Construction Services
Expense type = Construction Job Materials

Our best guess is that all of these should be mapped to Building and Construction card expense type.

How can we do the mapping of these if we only have one Building and Construction?
