Mixed inverted filters

Tellur

Hi,
awesome app!

It would be great if included and excluded filters could be mixed. For example:
Tag = "abc" AND Tag != "123"
That would show all entries with the Tag "abc" which do not also have the Tag "123".
In my work I need to register my times at the end of the week/month and it would be a huge benefit to quickly mark an entry as "registered" and use the entries list as a sort of "todo list" for this task.
In another software I use you can click a second time on a checkbox to invert it's meaning (it turns from a checkmark to a [-] symbol). I think that could work here as well.

Thanks!

This is also essential for billing with Subtotal. i.e.

I have tags that represent client names I want to bill 'Big Client'
When doing prior exports I had the export add an 'Invoiced' tag
Next billing cycle I want to invoice the client for anything that isn't billed yet
So I'd like to filter on Tag = 'Big Client' and Tag != 'Invoiced'

That would make the integration with Subtotal much easier.
