Lab Items with more than 15 associated charges

We need to have a way to bill for more than 15 associated charges on a lab item. We have some testing the have 20-30 charges on them. Support says we can build order sets but order sets are not used in Lab so they would have to remember on these tests that they would have to order in TWC Order Entry. Also providers/nursing do not think of order sets when they are ordering a single lab test and they will never remember which tests are built as order sets.
