Electronic Billing Codes

SOLVED

I am using Timeslips 2020.  We have a client who is converting to electronic billing.  They will be using LEDES1998B and require the MMLTS task codes (TC1, WC2, etc.).  Is it possible to use those codes in Timeslips?  All I can find in the Help section talks about the UTBMS codes, which I always use for other electronic billing clients.
