Timekeeper designations

SUGGESTED

I have several clients for which we create audit house files - usually LEDES 1998B, the problem is some require the paralegals to have the abbreviation PL and some require LA.  How do I set that up?  I don't want my timekeepers to have 2 different names and have to remember which one to use for which of our many insurance clients.  I'm not sure I can set this up in custom fields or in the audit house fields.  Can it be done through a template?  I'm not sure how to set this up.  What I have been doing for years (instead of figuring this out) is once I have the LEDES file I open it and do a global search and replace.  I would like to stop wasting my time on that, especially as some of the clients instead of batch billing require one, by one loading.  UGH!  Thanks for your help.
