Thunderbird allows the option for the message store to be an "inbox for different accounts" which includes a "local folder"option which allows a shared inbox for more than one email account served by that computer's Thunderbird.
Filters can be run from the local folders, and created from TB's "create a filter from message" menu item but currently quickFilters filter creation option from the right click context menu can only create them in user's individual email account folders. (Win 10 64 bit btw)
