I do have personal tasks into personal.org, and work tasks in work.org
(and many others).

Those files have FILETAGS (set to :personal: and :work:) so that I don't
have to manually tag every section, etc.

Then, in your clocktable, you can include/exclude clock information
based on the tag.

So, yes, what you ask seems possible to me!
