We have a lot of courses that are both ILTs and vILTs. Since we can't copy into vILTs, we have to create those.  If an ILT with the same name already exists, the old system would dynamically append characters to create a unique name.  In the new creation wizard UI, the onus is now on the client to ensure uniqueness manually (not sure why). Manually creating the unique name does provide more client control for naming conventions, so maybe that is why.

The primary issue is the timing of the check for the unique name.  The check should be at the time the name is entered and the Next button is clicked for that step, not at the end after the client goes through the steps for date/time/recurrence and clicks create. Throwing the error for the unique title at the end of the whole process requires backtracking and is inefficient.
