Storing user info in a separate database (not just a separate table)?

Thanks Scotty for a really nice Snippet! I’ve used it on one site, and I’m seeing its potential on another...

We want to use WebLoginPE to replace our existing custom code that handles our user form and inserts rows into a separate database. We have a fairly complex data model that is separate from MODx, so it lives in a separate database (not just in a separate table).

I’m going to tinker with this, but does anyone know off the top of their heads if the &customTable parameter can use the normal MySQL database.table notation (e.g. &customTable=`my_other_database.my_custom_table`)?

Thanks for any pointers.
