Creating a Site Collection in a New Content Database

Team,

I am looking to see whether we can create new site collections using SPA with an option to specifying a new content database. If you don't know already, a SharePoint Web Application can span multiple Content Databases, the limitation is at the Site Collection level.  Why this is an important concept is because of the fact that a single Content Database for a SharePoint Solution is not ideal, as the size can get very large quickly, and there is no easy way to move content out of a Content Database.

So typically I use the command line to acheive this .

Is there an option or parameter that can be included to allow the new site collection to be created in a new content database?
